Then, I sorted it by party and lifetime score, in that order, selecting the Republicans under 58 (chosen in order to barely include Susan Collins) and the Democrats above 50.

As for commentary, you take what you can get in some of the NE states. Glass half full, you know. However, in other states and districts, a conservative Republican would be a realistic goal, as with Toomey over Specter.

That was a very well-reasoned article in NR, by the way. FReepmail me if you'd like the spreadsheet file.
