Former South Carolina governor and congressman Mark Sanford is the latest Republican to consider a primary challenge against President Trump. Though he’d still lose, he’d be a much better person to make the case against Trump than former Massachusetts Gov. Bill Weld, or many of the other Republicans who have flirted with running.

Let’s get one thing out of the way to start — Trump is going to be the 2020 Republican nominee. He’s at an 89% approval rating among Republicans and has the ability to manufacture news cycles so that any other Republican who challenges him will be framed an ally of the fake news media and radical anti-American Left.
