Conservatives can win any state as long as the right candidate is on the ballot. A pro-life conservative is now governor in Maine. Why do we assume that Republicans can only win in red states?

There are competing and mutually incompatible visions of society, and they have gradually become geographic in nature.

It does not matter who the conservative is, they cannot win in a statewide race in any of those states.
