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).
Probably, there's been progressively more ideological sorting of the parties every decade.
Still, those elections where the candidates are running with the "wrong" parties are fun to look at.
A typical near-tie election in Massachusetts: 2010-Sen. Special, moderate conservative Republican Scott Brown beats liberal Democrat Martha Coakley 52-47.
Bizarro Massachusetts: 1990-Gov, moderate libertarianish Republican Bill Weld beats ultraconservative (except pro-single payer and anti-death penalty) Democrat John Silber 50-46:
Weld won Cambridge and Provincetown, either of which is the equivalent of a Republican winning Berkeley, CA.
