To be clear, my bet is that this is somebody having fun with editing. The FJB is just too loud for it to be at a Baraq rally for Mr. Magoo.
It fooled me the first time through. It's doctored for sure but it still has meaning. The two individual parts of it are true, just didn't happen at the same time. A huge crowd, way bigger than Obama would draw now, was saying FJB, and in a way, same goes for Barack, but they wouldn't be at his rally. He [Barack] picked Biden, his advisers run him, his policies did this to our coumtry and he's out there bragging about it. They are not saying FBO but they might as well be.
I'm glad they're not still doing that, it's not very dignified. Simpler is to just campaign and vote his losing agenda out.
