Name one palatable to ME voters that exists outside Collins.

Who as a pro-choice Republican vs. pro-life Democrat John Baldacci produced this hilarious result in the 2002 gubernatorial election:
I think those days are a thing of the past. Not necessarily pro-life Ds or pro-choice Rs, but when you could actually get a matchup for a major statewide election with that combo. These days, when the Republican is pro-choice, the Democrat almost certainly is as well (and vice versa).
Pennsylvania's 1990 gubernatorial election is a major example of that. That's an election in which I would have actually voted for a Democrat.
