Yes, Scalise is quite far right -- but he is at least a man who thinks and acts with some deliberation. That's important. Jim Jordan would be absolutely hopeless at trying to unite the Republican conference, and that will be crucial to going forward. In other words, Scalise is an unpleasant choice, but Jordan is freaking scary. Yet sometimes it is necessary to choose the lesser of evils in order to avoid falling into the abyss.
Yet, news seems to suggest that McCarthy allies are working quietly against Scalise. I'm not clear on why.
Jim Jordan, on the other hand, was very definitely a player in January 6. Cassidy Hutchinson has testified he was privy to all of what was going on that day, and that later he worked feverishly to "stop the steal," making entirely baseless claims of election fraud. That would definitely seem to suggest that he is as disinterested in preserving American democracy as Trump is.
So, since the Democrats will never be able to get someone of their own choosing to clutch the gavel, they might be wise to support a nose-holder who will at least keep democracy alive.
