Dumb:

Of concern to McCain’s campaign, however, is a remaining and still-undisclosed clip from Palin’s interview with Couric last week that has the political world buzzing.

The Palin aide, after first noting how “infuriating” it was for CBS to purportedly leak word about the gaffe, revealed that it came in response to a question about Supreme Court decisions.

After noting Roe vs. Wade, Palin was apparently unable to discuss any major court cases.

There was no verbal fumbling with this particular question as there was with some others, the aide said, but rather silence.

This is apparently one of those “embarrassing” Palin clips CBS has been sitting on.

Obviously, one would like a political leader to be familiar with the major Supreme Court rulings.  Hamden.  Marbury vs. Madison.  DC vs. Heller.  Kelo.  Etc.  And I’m confident that Palin is undoubtedly familiar with a lot of the major SCOTUS cases, but just because she doesn’t immediately spew forth a list of them when the question is popped on her in the midst of an interview is hardly commentary on her judicial knowledge.

Think about it.  Has anyone ever surprised you with a question about something you know but suddenly forgot?  Someone once asked me how old I was and I had to stop and think about it for a minute.  Now combine that perfectly human tendency with a high-pressure interview with someone you know is trying to trip you up and Palin’s brain freeze suddenly doesn’t seem all that unreasonable.

If you think being President means being able to immediately run down a list of prominent SCOTUS rulings the moment Katie Couric demands it then no, Sarah Palin isn’t ready to lead.  But the reality is that that sitting in the Oval Office and making decisions is a much different thing than dealing with heckling journalists determined to make you look stupid.
