The party doesn’t care about him, specifically. His polling has been under water for months, and anyone who’s not utterly delusional knows he’s about to get thumped by Stein. They’re now worried that if he stays in the race over the next month and a half, he will continue to be a lightning rod for Democratic attacks, especially on abortion, and that’ll continue to dampen Trump’s messaging. Still not convinced NC could go blue, but if it does, Robinson will be hugely responsible for it. He’s a fucking moron who makes Trump look sane and stable.
