James Carville wasn’t horsing around.

The famed Democratic strategist said attending the Kentucky Derby convinced him that “buyer’s remorse” was growing among Donald Trump voters.

“It’s not just that the polling is bad; you can feel it,” Carville said on “Politics War Room” Thursday. “You can just see the anger coming from people that you ... would never expect.”

“I saw it at the Kentucky Derby,” he continued.

Carville described sitting with James Williams Jr., the general president of the International Union of Painters and Allied Trades. He said Williams informed him that most members voted for Trump, but “they got real buyer’s remorse now, which I think is a good sign,” he said.
