More than a dozen interviews with high-profile GOP financiers revealed a pervasive confidence that the party’s rank-and-file voters will ultimately reject Trump’s brand of politics.

“He is going to implode himself,” said Frank VanderSloot, chief executive of an Idaho nutritional-supplement company who is backing Sen. Marco Rubio (Fla.). He said he recently turned down a funding request from a group seeking to run anti-Trump ads.

“It’s just going to take a little time for people to take a step back and look at his track record, see who he is and how he’s changed his positions and how unprepared he is to be president of the United States,” VanderSloot said.

That view is shared by Andrew Sabin, a major New York donor supporting Bush.

“I’m not worried,” Sabin said. “The voters are not going to think out their candidate until a week or two before they go into the voting booth.”
