This list doesn't add much to what is already posted in this thread. Hard to take serious anyone listed behind Bernie Sanders, Terry McAuliffe, and others. But who knows?

Here, in roughly ascending order of feasibility, are 21 prominent or semi-prominent Democrats who could step up for a 2016 presidential run:
Dannel Malloy
Malloy was supposed to be headed for a tough 2014 re-election race for governor of Connecticut, but he ended up winning easily. A spokesman said he was not interested in the Oval Office — but also indicated the Washington Examiner is not the first publication to ask. "As the Governor has said repeatedly, he loves his current job as Governor of Connecticut and has no interest in running for President," Malloy's office said. "He believes that should Secretary Clinton become a candidate for President, she has the outstanding credentials, experience and record to be a very strong candidate."
Tom Udall
The son of a Kennedy-era secretary of the interior and nephew of a powerful Arizona congressman, Udall won a senate seat in New Mexico in 2009. He brings no youth at age 66, but he hails from American royalty. Udalls have had starring political roles in the American Southwest for more than a century. Is it time for a President Udall? Udall declined to comment.
Bernie Sanders
Vermont's junior senator is the most prominent (out of the closet) socialist in American politics, a status that makes him a favorite with reporters (because he gives good copy) and the Democratic base (because he's a socialist). Strangely, the usually forthright and garrulous Sanders has turned coy about his previous 2016 talk. Sanders told Politico Friday he was not eager to run "a poor campaign" that was "not well funded," adding that he had not raised much money. The 73-year-old did not respond to Examiner requests for comment.
Jay Nixon
For better or worse, the Ferguson riots made the governor of Missouri a national figure, and he declined to give a flat "No" when Politico asked him about being a potential Hillary replacement in February — before the email story broke. Nixon did not respond to requests for comment.
Bill Nelson
At 72 years young, the senior senator from Florida is a reliable liberal who occasionally finds common ground with Republicans on defense and intelligence votes. He would also be America's first spaceman president, having traveled into the vacuum as a payload specialist on space shuttle Columbia in 1986. A Nelson spokesman told the Examiner his 2016 answer "is a no."
Martin Heinrich
That New Mexico boasts two Democratic senators is a rare success story for the party. Registered Democrats outnumber Republicans by a 3-to-2 ratio in the Land of Enchantment, Democrat hold large majorities in both chambers of the state house, and Republican Gov. Susana Martinez runs moderate to liberal on the GOP spectrum. Nevertheless, Heinrich — though he toes the party line on abortion and environmentalism — is careful to shore up conservative appeal. While he now supports gay marriage, the epiphany that brought his deeply held beliefs into compliance with Democratic Party norms came very late — in 2012 — and only when a primary opponent attempted to flank him on the issue. He opposes the federal "assault weapons" ban. He is just about as handsome and untested as Barack Obama was in 2008. Heinrich declined to comment.
Tom Wolf
A one-time forklift operator with a Ph.D., Wolf successfully ran his family's York-based building materials company for 30 years, before spending a generous chunk of his fortune on a successful 2014 campaign for governor of Pennsylvania. He has assumed office at a time when the Keystone State has nowhere to go but up. GDP growth was anemic under Republican predecessor Tom Corbett, and the city of Chester boasts the second-highest violent crime rate in the country. None of that may add up to a presidential profile for the 66-year-old, but Democrats could use a candidate who has not spent his life seeking one political office after another. Wolf did not comment.
Steve Beshear
Governor of Kentucky since 2007, Beshear has followed a familiar economic-management pattern, with predictable results: A scheme to lure manufacturing of environmentally correct Zap cars went nowhere, as have his efforts to get the Bluegrass State a bigger share of the declining casino gambling business. Kentucky has nevertheless enjoyed reasonable prosperity during his administration, and with two of the Republican Party's most prominent senators, it's the kind of state Democrats need to know how to win. Beshear will be 71 next year, and while fans frequently propose him as a prospective Hillary Clinton running mate, he declined to comment for this article.
Al Gore
What Democrat can ever forget that Al Gore beat George W. Bush in the popular vote in 2000? Like many folks on this list, the two-term vice president is of a certain age. But he has not been idle in his 66 years, having amassed a fortune estimated at $200 million. Various media have quoted anonymous sources saying Gore — whose work history includes honorable service in Vietnam and employment as a journalist, senator and knockabout presidential candidate even before environmentalism made him a Nobel laureate – is interested in a 2016 run. Gore did not respond to requests for comment.
Amy Klobuchar
The senior senator from Minnesota can't quite boast of having appeal in a battleground state: Her colleague Al Franken, also on the Democratic-Farmer-Labor Party ticket, snoozed his way to re-election last November. A Republican wave across the great lakes region has failed to reach the Gopher State, where the DFL still holds the governor's office and one house of the legislative branch. Which means at this point, big labor may need a Minnesotan, and Klobuchar does her part, most recently lamenting U.S. Steel's decision to close a major plant by noting that she's in contact with Local 2660 about the matter. She declined to comment and remains an outside bet at best.
Joe Manchin
If the Democrats are interested in again finding the center of American politics, they could ask West Virginia Sen. Joe Manchin the way. Republicans have repeatedly tried to lure him to switch parties. Crucially, he is untainted by Obamacare, having come into office after the Affordable Care Act was enacted, and he is generally pro-gun and pro-coal. Although he'd be running from the Senate, Manchin has executive experience as governor of West Virginia. So far he has made no 2016 moves. Nor has he ruled out the possibility of a run. "I'm not serious about running," Manchin told a West Virginia CBS affiliate. "On a national ticket, it would be a pretty far reach probably for me."
John Hickenlooper
The governor of Colorado could put together a coalition of labor, hipsters and louche libertarians. A secession movement during Hickenlooper's administration went nowhere. A concentrated backlash against his extremely broad gun control law cost several Centennial State Democrats their jobs, but Hickenlooper is still around. He declined to comment.
Rahm Emanuel
Emanuel combines the vices of Andrew Cuomo (unions hate him) and Terry McAuliffe (clinging Clinton odor). On the plus side, Chicago's GDP has grown 10.5 percent since he assumed office, and despite widely reported murder spikes, the city's violent crime rate has declined on his watch, according to a database of violent crime statistics from all law enforcement agencies in cities with populations more than 25,000. Wealth in Chicago is highly concentrated, and Emanuel is highly connected there and in Los Angeles. He declined to comment to the Examiner.
Cory Booker
Booker's passion for retail politics gave him a national profile even before he became mayor of Newark, N.J., in 2006 (the 2005 documentary "Street Fight" details his first, unsuccessful attempt to beat the Sharpe James machine). He ran the Brick City with a penchant for colorful — usually unverifiable — tales of hands-on constituent service. Since joining the Senate in 2013, Booker has more than once found common ground with likely Republican presidential candidate Rand Paul of Kentucky. He declined to comment on the 2016 election.
Jerry Brown
A fixture of California politics since the time of Zorro, Jerry Brown will be 77 next year. But he is an American original whose idiosyncratic career includes a serious challenge to candidate Bill Clinton in the 1992 primary (Brown ran on a flat-tax platform) and a lifelong desire to become president. Now in the second term of his second tenure as California governor, Brown has arguably been a more conservative executive than his Republican predecessor Arnold Schwarzenegger. He's also remarkably popular, though claims of a broad California recovery don't bear scrutiny. But he says he's no longer eyeing the Oval Office. "Running against Hillary is like running against Jerry Brown in California," Brown told the Washington Post Friday. "In the Democratic Party, it's not going to happen."
Terry McAuliffe
A gleefully political animal, the current governor of Virginia had the good fortune of following Republican Bob McDonnell, whose recent conviction on corruption charges softens McAuliffe's own reputation for pushing the limits (of good taste if not political ethics). McAuliffe is a longtime Clinton crony, but intriguingly, he said last year he has no intention of helping her campaign. "I've done that," McAuliffe told Richmond's NBC affiliate. "It's been a great part of my life, but to be honest with you, I'm past the politics, I'm now into governing."
Andrew Cuomo
Cuomo wouldn't comment to the Examiner about his presidential thoughts, but he is one of the Democratic Party's most effective fundraisers, and he's the governor of the not-inconsiderable state of New York. The Empire State's dire finances sometimes put him at odds with the labor unions essential to all Democrats. Idealistic leftists — who will be crucial in the primaries — have no passion for him. Last year unnamed Cuomo associates told the New York Post the son of Mario Cuomo is keeping his powder dry for 2020.
Jim Webb
Webb has one of the most impressive résumés in America: Vietnam veteran with a Silver Star, two Bronze Stars and two Purple Hearts; Reagan administration secretary of the Navy; Emmy-winning journalist; inspired author of both fiction and non-fiction; and former Virginia senator who chose to leave office after one term. He told Politico last year he could run a "first-class campaign" reminiscent of his upset over Republican Sen. George Allen. Webb is a Jacksonian Democrat, a type of populism with potentially broader appeal than Warren's professorial jabs at inequality. That could also be his Achilles heel: The Democratic base has moved steadily leftward, and Webb's Scots-Irish candor and emotional patriotism make him a tough sell in the primaries.
Martin O'Malley
O'Malley completed two terms as Maryland governor this year, and his legacy is mixed at best. In a very surprising upset, Old Line State voters elected a Republican over his chosen successor, and painful memories of his "rain tax" and other schemes linger. But he is on record as wanting to run, and "Vote for M.O'M" is a campaign slogan that writes itself. On MSNBC this week he criticized Clinton over the email scandal and said he would decide this spring whether to run.
Joe Biden
The vice president is one of a handful of Democrats who have expressed verbal interest in running for president next year. "There's a chance, but I haven't made my mind up about that," he told ABC in January. "We've got a lot of work to do between now and then. There's plenty of time." Biden is hamstrung by his age, a strong habit of putting his foot in his mouth, and an even stronger habit of putting his hands on uncomfortable-looking women during photo ops. But he is the Democrats' sort-of-lovable uncle, and his current job is a natural — though far from guaranteed — springboard to a presidential run.
Elizabeth Warren
The freshman senator from Massachusetts provided much of the intellectual firepower for Obama-era innovations like the Consumer Financial Protection Bureau. More than any other potential candidate (Clinton included), she speaks to the hard economic Left that provides most of the party's grassroots energy these days. When Democrats look in their hearts, it's Elizabeth Warren they see. Warren repeatedly disclaims any interest in a 2016 run, a stance she has maintained through Clinton's current troubles and repeated when asked by the Examiner.
