Well, Hillary or Obama sure as hell won't appoint strict constructionists, that's for sure. I'm not saying McCain will win the Republican nomination, but if he does, he'll be a better bet for strict constructionist judges than a Democrat. Any of the Republican candidates would. That's the point the girl was making to these "take their marbles and go home" people, the ones who say they won't vote for McCain (or Huckabee, or Romney--whoever it is that doesn't come up to their brand of snuff), and would rather have a Democrat president than soil their so-called ideological purity by voting for the "leper" Republican.
McCain wouldn't dare put a constructionist judge before his friends on the left for confirmation. He has too much regard for their time to waste it like that.
