UPDATE: On CBS Evening News Wednesday evening October 1st, Katie Couric spoke with Sarah Palin and Joe Biden about Roe v. Wade and the separation of church and state.  Watch video and read Scott’s post.   

Politico reports that in a remaining clip from the CBS interview with Katie Couric, Sarah Palin has yet another embarrassing blunder.

When asked to discuss Supreme Court discussions other than Roe v. Wade, Palin had no response:

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.
