We need a Republican third-party candidate who won’t just primary Trump but will get on the general election ballot and challenge him in 2020 in all 50 states — but do it from his right, not from the center.

Yes, we need a Republican who will do the most high-minded, patriotic thing I can imagine today — fall on the Trump grenade. That is, run against Trump from the right in the national election as, say, a libertarian — who could oppose Trump for his tariffs, his piling up of the national debt, his opposition to immigration and his immorality. This could siphon off just enough Republican votes for Trump to lose close races in Wisconsin, Michigan, Ohio, Pennsylvania, Nevada and Florida. We need a Republican who will do to Trump what Ralph Nader did to Al Gore in Florida in 2000.
