Nah, Trump really is just plain freakishly crazy, and he's demonstrating why the GOP was wrong to cultivate the other crazy extremists to form their party base. The GOP is disintegrating ONLY because of their own choices; they are and remain their own worst enemy. Sadly they are equally injurious to the nation, and to the principle and fundamental concept of representative government.
They have come back to bite the GOP in the rump, which rhymes with Trump.....which stands for LOSE!
