Poll: GOP favorability reaches seven-year low; 60% of voters say nominating Trump is bad for party

The survey, conducted Friday through Monday, shows a high level of upheaval within the GOP as Trump trails Clinton by 12 percentage points in the horse race. Among self-described Republicans, 28 percent say they feel unfavorably about their party. Just 4 percent of Democrats say they feel that way.

“You typically see near-universal approval of the party by party members,” Selzer said. “As recently as December of 2014, just 9 percent of Republicans said they were unfavorable toward the Republican Party.”

Sixty percent of likely voters say nominating Trump next month at the party’s national convention in Cleveland is bad for the Republican Party. Among likely Republican voters, 27 percent hold that view, while 69 percent say he’ll prove good for the party.
