The feeling on Wall Street that Republican Donald Trump would have no chance of winning the presidential election against Democrat Hillary Clinton shows the disconnect with Main Street, said Gary Emineth, an unbound delegate from North Dakota who supports the billionaire businessman.
According to the latest CNBC Fed Survey, 80 percent of respondents see Clinton winning the presidency this November, with no other candidate even close. Just 13 percent of the 48 respondents believe Trump will win the White House.
"The people are behind Donald Trump. You're going to see a rally behind him when he wins the convention in July in Cleveland," Emineth told CNBC's "Squawk Box" on Tuesday, as Connecticut, Delaware, Maryland, Pennsylvania and Rhode Island held primaries.
Pennsylvania represents the biggest prize with 71 delegates up for grabs.
Despite expectations to the contrary, Emineth said he does not see a contested convention beyond one ballot, expressing confidence that Trump will amass the 1,237 delegates needed to clinch the nomination.
Emineth, formerly head of the North Dakota Republican National Committee, estimates about 300 to 450 unbound delegates are going into the convention because of the different rules in various states.
"[Even] if Donald Trump is 50 to 100 [delegates] short going into it, he will get his fair share of [the unbounds] and that's why he'll win on the first ballot," Emineth said. "People want to elect a winner."
Trump hasn't even started focusing on Clinton yet, Emineth said.
