In this Twitter thread. It’s pointless to try to argue policy with Trumpist true believers so long as they remain true believers.
Instead, I would suggest focusing on reaching out to the unmotivated who sat by and allowed Trump to take power because they didn’t care enough about either side. Then there’s those who were simply too disgusted by both sides to vote for either. On that latter subset of voters: in a world where, as Marx observed, “the oppressed are allowed once every few years to decide which particular representatives of the oppressing class are to represent and repress them,” why wouldn’t they be?
Also, focus on the disenchanted; some (not all, you can not count on it being all or even most) Trump voters will, after enough pain, start to question their decision and can be peeled off from his base. We’re already starting to see that with some capitalists and farmers getting queasy about the trade wars Trump is starting.
But there’s going to be true believers that stay true believers. Heck, there’s still Hitler and Stalin fans out there, who believe their idols have been massively unfairly treated by the opinions of a misinformed public. Trying to convert such people with facts and logic is mostly a wasted effort.
