What would make Trumps base supporters turn on him?

no the Korean war has not “ended” until there is something definitive in writing

I don’t know if that is a joke or not, but I believe the unmoving base is evidenced by poll numbers, not individual breaking points. So if we see a steady support of 42% regardless of what Trump does or what crazy shit is reported about him, that’s what people are referring to as his base. Not some dude whose straw that broke the camel’s back is that Trump did not sit cross-legged at a sumo tournament and is now wondering if he is part of Trump’s base.
