@curiousgawker oh, I would frame that slightly differently: it's not that he was found guilty of interfering with an election but that he was found guilty of lying.
The reason I frame it that way is because in the course of this case Trump wasn't merely bloviating or exaggerating or using the other language that his supporters have always excused. Instead, he was flat out lying to his supporters about substantial matters, things like lying about what he was actually charged with for example.
Trump supporters don't care about the election interference. But it is possible that they might start caring if their own loyalty was being betrayed, if they started to notice that Trump is lying to them about these starkly factual issues. It's part of the railway to undermine the guy.
Unfortunately it seems too late to change strategy now.
