According to this article in The Hill, the Senate's five presidential candidates weren't there to vote on whether or not Mike Mukasey, who doesn't understand that waterboarding is torture, should be attorney general.
Hillary Clinton, Barack Obama, Joe Biden and Chris Dodd had all promised to oppose the Mukasey nomination but they couldn't be bothered to show up and do it.
They wouldn't have made a difference, but they would have made a 53-40 vote much closer had they been there to oppose.
Also, Evan Bayh, Diane Feinstein, Ben Nelson, Mary Landrieu, Charles Schumer, and Thomas Carper are all aleged Democrats who are no longer worthy of your support. Of course, Joe Lieberman showed once again why the people of Connecticut made a big mistake last year.
This should have been a slam dunk rejection.
The only argument against sinking this nomination is that Bush would have just kept a temp in place for the rest of his term and the temp would have been worse than Mukasey. But that's a weak argument. Congress should have left Bush with an illegitimate AG.
