*Two of Republican presidential candidate Ben Carson’s top paid advisers have just jumped ship.

The GOP candidate’s campaign manager Barry Bennett and senior campaign spokesman Doug Watts are “out” as of Thursday, according to Carson’s Iowa director, Ryan Rhodes.

They couldn’t even stick around for the Iowa caucuses, which are only a month away.

Watts and Bennett announced their resignations effective immediately in a statement, saying they respect the retired neurosurgeon and have enjoyed helping him reach “top tier status” in the crowded Republican field.

“We are proud of our efforts for Dr. Carson and we wish him and his campaign the best of luck,” Watts wrote.

Carson has plummeted in national Republican presidential polls. In an interview with The Associated Press last week, Carson indicated he was moving toward a major shake-up of his campaign.

Hours later, he tried to walk back that message and said his senior team “remains in place with my full confidence.”

Guess not.
