Add Michael Steele to the list.
Steele, the former Republican National Committee chairman, will not vote for Donald Trump, the GOP presidential nominee.
He made the announcement Thursday at a San Francisco dinner hosted by the liberal-leaning Mother Jones magazine, according to BuzzFeed.
Trump, said Steele, has "captured that racist underbelly, that frustration, that angry underbelly of American life and gave voice to that."
"I was damn near puking during the debates," said Steele, adding that he believes Trump represents only 30 percent of the Republican Party.
In recent weeks, dozens of Republicans have condemned Trump for his lewd comments about women, and some have pulled endorsements, announcing they will not support his campaign.
While some Republicans have said they will in turn support Hillary Clinton, the Democratic nominee, Steele, who served as chairman from 2009 until 2011, is not one of them.
"I will not be voting for Clinton," he said, without announcing who he'll support in next month's election.
