Mark Levin was half-joking but predicted this. He said Sununu, Larry Hogan and Chris Christie need to get together, preferably not on a boat. Because they will be over the weight-limit. Then decide on one NeverTrump candidate. Looks like it will be Sununu.
I still think it’s not out of the realm of possibility that Cheney or Romney could be it, and they could enter relatively late in the process.
