I agree hard to believe it is him at least alone.
I can understand he may have been privately insulted by DJT (who has not been?) as reported as a somewhat supported theory from a Meghan Kelly podcast and
as a cause to not support DJT much anymore.
Nonetheless, the site is a total mimic of Democrat Party talking points which I did not see Matt supporting in the past. OTOH some previous Rs hate DJT so much they go on enemy stations and sound like Dems/libs/progressives.
