"When people ask about are you definitely going to vote for him, are you definitely going to vote against him, realistically, you got to be at least in the 40s, mid-40s on that question, and he's sort of in the low 40s," he continued. 

"As far as his reelection prospects right now, they are in some jeopardy, and that's on the big assumption that he runs," he said. 

A new Hill-HarrisX poll shows Trump's approval rating at 45 percent.
