Romney deserves to be shunned.
McConnell should ignore him for the rest of his term.
He is a man without a country.
Elect enough senators to make up for Collins, the Alaskan Sea Kow & Romney and McConnell can afford to!
Until then Romney will have to be bargained with.
I think he was going to pay that price anyway and can now say it was revenge in hopes to spare himself. His son is caught up in Ukraine money and probably is about to be exposed. His adviser has gotten money from Brumisma. My guess is that Romney has a Ukraine problem also and knows it is going to be exposed.
