Today is a sad because it marks the last of the awful CBS interview tapes that have been released showcasing Sarah Palin's lack of knowledge about well, everything. In her latest, and probably greatest misstep, she can't name one other Surpeme Court decision besides Roe v. Wade. And when pressed further she names...Roe v. Wade.

You can check out the video above. For comparisons sake, I've included the section where Joe Biden gets asked the same question and doesn't miss a beat, but if you want to skip to the Palin goodness, go to the two minute mark. Here's a transcript of her answer, but paper does not do it justice:

(after being asked to name another decision)

PALIN: Well, let's see. There's --of course --in the great history of America rulings there have been rulings, there's never going to be absolute consensus by every American. And there are -- those issues, again, like Roe v Wade where I believe are best held on a state level and addressed there. So you know -- going through the history of America, there would be others but--"

COURIC: Can you think of any?

PALIN: Well, I could think of -- of any again, that could be best dealt with on a more local level. Maybe I would take issue with. But you know, as mayor, and then as governor and even as a Vice President, if I'm so privileged to serve, wouldn't be in a position of changing those things but in supporting the law of the land as it reads today.

The debate is TONIGHT! I feel like it's Christmas Eve or something.
