Republicans should be the party of Wahlberg, not the party of Schwartz. (I believe you're getting hung up on that point - maybe now we're clear.)
Those Republicans could then work with non-moonbats, regardless of party - say, Dale Kildee on a pro-life issue (or did he give that up finally?), Ron Paul on monetary policy - to pass a strong agenda. Get the non-moonbats (moderates, libertarians, blue dog, fiscal con, whatever) to work for us, instead of the reverse, as often happens today. If we replaced every Carolyn Cheeks Kirkpatrick and Carl Levin with an Alan Simpson and Erskine Bowles, it would be a simple matter to turn around the country.
