And the McCain appointees would be any better? Remember, it was Republicans of a McCain stripe who gave us Earl Warren, William Brennan, Harry Blackmun, John Paul Stevens, and David Souter. McCain has already said he would NOT appoint strict constructionists of the Alito type. They're too conservative (and besides, they'd be likely to strike down McCain-Feingold.) So this is a non-issue.
I don't think so. Yeah, those other Republican appointees were horrible. But none of them were as bad as Thurgood Marshall, Ginsburg or Breyer. Also, even Bush 41 appointed Thomas, and Bush put in Alito and Roberts. Sometimes we get lucky with the RINOs, but we NEVER will with a Demonrat.
I know he wouldn't appoint an Alito - to McStain's dishonor. But he said that he'd appoint someone like a Roberts. To me there is little difference - and, again, at least you have a chance. Hillary will nominate Schumer or Spitzer types. Do you want that?
