Foolishly perhaps, I wonder if the rug will be pulled out beneath Trump as his supporters, in the face of growing evidence, realize they've been played for chumps by a purely self-serving swindler who thinks they're too stupid to notice. Not all of them, because he will always have the KKK vote, but enough of them to severely damage his approval rating and make his allies in Congress sweat.
Will there be a last straw, for decent people (yes, there are some) who voted for Trump? I know they are out there. But I've given up speculating on what the tipping point might be.
