Republicans who cannot support Donald Trump as the party’s nominee should skip next month’s convention in Cleveland, former House Speaker Newt Gingrich said Wednesday, tearing into factions of the party for appearing ignorant of national and even global political attitudes.

“You know, if you can’t vote for the nominee of the party and the person who got the votes, don’t go to the convention,” Gingrich said during a Facebook livestream on a trip to Hungary with his wife, Callista. “Don’t think you can safely get away with imposing your values, your judgment, your wisdom on the people of the United States. That era’s over, and in fact, you’re going to look very foolish arguing that the voters — your voters — back home don’t count because you’re so much smarter.”

Even as Republicans have lamented the Democratic superdelegate process as hurting Bernie Sanders, Gingrich remarked that “some of our friends want to create elite delegates in the Republican Party.”
