Is he a liberal Republican in the vein of Javits and Mathias who can say that is fed up with the party of Trump, or is he a run-of-the-mill conservative who does this solely out of political expediency?
Considering he was a Republican under Trump's first two years, Romney, McCain, Bush 43, Dole, Bush 41, etc., I think it's safe to say he's no Javits and Mathias and just wants to save his own (electoral) ass.
Yeah he won only by 607 votes last year he may be liberal on one set of issues but hes clearly just trying to save himself
