re: What the hell was Trump thinking by supporting Strange?

It was definitely a political error. These things happen. I live in Alabama. Strange didn't have a chance. And even if he did have a chance he shot himself in the foot with his campaign against Brooks. You can't run a campaign against a guy that is part of the freedom caucus and portray him as a Pelosi twin and then think his voters are going to come over to you in the runoff

Strange ran a 100% negative nasty campaign in both the initial Primary and the runoff. I really have no idea why he thought that strategy was a winner
