Ralph Rossum compares Sotomayer with Souter: They’re both liberals, so what’s the big difference? She is younger by 16 years, and much more aggressive. But I think the real ideological disposition regarding race and ethnicity, as Stuart Taylor and George Will note, should be the major public issue discussed. Of course, it will not be a disqualifying issue, but that’s not the point. What the GOP should do is to use the identity politics issue to draw her out, or even better, her supporters (including Obama), and make a powerful and useful political argument against that position. That, combined with how the public will perceive the government takeover of GM, could become major campaign issues. Not only are the Democrats vulnerable on both, but even middlin’ Republicans ought to be able to make arguments on these two matters.
