I found this passage buried in the body of an article about the concerns of the GOP over Trump:
https://thehill.com/homenews/senate/4657...sing-week/
Quote:An AP VoteCast found a significant percentage of Republican voters in the Iowa caucuses and New Hampshire and South Carolina primaries would be so dissatisfied with Trump as their party’s nominee that they wouldn’t vote for him in November.
Specifically, 20 percent of Republican caucusgoers in Iowa, 34 percent of GOP primary voters in New Hampshire and 25 percent of GOP primary voters in South Carolina said they were so dissatisfied with Trump that they would not vote for him in the general election.
