This is a nakedly political decision. Again, I'm not holding my breath for repercussions. The electorate has seen a Republican party incapable of governing (at least going back to 2000) and have rewarded them with more power. From my biased view, the more audacious and brazen the GOP is in disrupting political norms and traditions, the more support they get from the base.
Perhaps there's a tipping point. If there is, and we have not yet reached it, I both wonder if we ever will, and the damage that will have been done to get there.
Stuff is messed up.
