As we know, the only political skill that Trump has is to throw red meat to his base. For the first two years of his administration, that had some effect; the GOP controlled both houses of Congress, and the real short-term threat to a large number of incumbents was a primary challenger, not the Democrats, so appeals to the base were a useful way of keeping wayward Republicans in line.
Today, not so much. Trump can huff and blow and appeal to the base all he wants; Nancy Pelosi doesn’t have to care, and she won’t.
When will Trump figure out that his one trick doesn’t work anymore? He’s slow, so it won’t happen overnight.
