Until Washington changes and provides an acceptable alternative, Trump can not only shoot someone on 5th Avenue, he can get caught in the Kremlin on Vladimir Putin’s desk with a goat, and his supporters won’t care. They expect Trump will say, “Fake news! Fake desk! Fake goat! Maybe a younger, hotter bovid, but not this one!” They are good with that.
Trump is still all that is standing between his supporters and the return of the establishment.
