Conservative columnist George Will said Friday that he's leaving the GOP over Donald Trump's rise to becoming the party's standard bearer.

Will suggested that a Democratic victory in the presidential election in November would be preferable to Trump winning the White House.

"Make sure he loses," Will told PJ Media, a conservative blog. "Grit their teeth for four years and win the White House."

He said he changed his voter registration from "Republican" to "unaffiliated."

"Generosity. That was my first mistake."
"Experience must be our only guide; reason may mislead us."
"Instagram is Twitter for people who can't read."
