Longtime conservative columnist George Will is wiping his hands clean of the Republican Party.

"This is not my party," Will told PJ Media on Saturday. The Washington Post writer said a Democratic presidency would be better than the alternative offered by Donald Trump -- who once called Will a "major loser."

“Make sure he loses," Will said of the presumptive GOP nominee. "Grit their teeth for four years and win the White House."

His voter registration in Maryland has now changed from Republican to "unaffiliated," PJ Media reported. The final straw was House Speaker Paul Ryan's (R-Wis) endorsement of Trump, he said.

In the meantime, Trump continues to fumble over himself. Just this week, he fired his campaign manager Corey Lewandowski before setting off to Scotland to promote his golf resorts.

“He had one good day because he didn’t vomit all over himself and gave a decent speech,” GOP consultant Matt Mackowiak said of Trump.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
