For that matter, I think Schwartzeneger's platform is improving in clarity. I just think that Republicans who aren't following Duf Sundheim's lead and sticking with the party line that we have several (now two?) good Republican candidates are just hurting our chances of winning. No matter which candidate does better in the long run -- the one with star power, or the one with the conservative identity -- we won't get there by dragging one or the other through the dirt.
I like McClintock. Some like Schwartzenegger. They're both great candidates. People who attack either one based on the electability issue (i.e. from one side or the other) are just splitting the party and leaving both candidates in a lurch with Democrats. Both candidates need to sell themselves to the Democrats, remember that.
