I think it is entirely possible that the Republican Establishment deserting Trump could be what brings him back to life. He won being an outsider. Neither Biden nor McConnell and co. can claim to be outsiders. Throwing Trump under the bus could be just what that idiot needs to be competitive again.

Barring that or Trump finding a better strategy than his current lame-ass Hillary 2.0 plan, I think Biden will win in November, as impossible as that seemed only a few months ago.
