Charles Krauthammer told viewers Friday on “Special Report with Bret Baier” that Donald Trump’s presidential candidacy has “become normalized” among those in the mainstream Republican party.

“You get one or two [who] start to endorse Trump essentially as a signal that it’s ok,” Krauthammer, a syndicated columnist and Fox News contributor, said.

A new Fox News Poll released Friday revealed two tiers on the Republican side of the race for the White House: Donald Trump leads the pack with 34 percent with Ted Cruz behind him at 20 percent, Marco Rubio at 11 percent, and Ben Carson at 8 percent. The second tier consists of the remaining GOP candidates who are at 4 percent or less.

However, the poll also asked GOP primary voters whether there is any candidate they couldn’t support against the Democratic nominee in November. Trump topped that list as well with 15 percent saying they would refuse to vote for him.

“The number of people who are against him, Republicans, six, eight months ago was about 60 percent, 59 percent. If you’re down to 15 percent there’s an acceptance,” Krauthammer added.
