Massie went down yesterday. Cassidy lost a few days ago. Cornyn will probably follow shortly. In spite of inflation, the war, and everything else, Trump’s voters remain loyal to him and punish normie Republicans who show any sign of independence. That is why GOP politicians are such cowards; they know they can ignore the great man on some issues of policy that he doesn’t care much about, but any kind of personal challenge is verboten and will result in political oblivion.
But Trump’s purges come with a risk; the number of lame duck normie GOP members of Congress with little left to lose from displays of independence is increasing. Some of them, like Tillis, are showing signs of a spine. Cornyn is such a GOP institutionalist that he probably will continue to go along, but Cassidy may not. If you add the lame ducks to Collins, Rand Paul, and Murkowski, you have the potential for adverse votes in the Senate. Then what?
Probably more autocracy.
