Seems like Dems propping him up so he doesn’t need the alt-right would have better than giving the alt-right more control of the party.

McCarthy is the far right. Just because there’s another faction of the far right that’s turned against him doesn’t change that, and it certainly doesn’t make him worth allying with. The Democrats tried a policy of spinless complacency for thirty years. It didn’t work. It’s not going to start working now.
