Katie Couric: What do you think is the best and worst thing that Dick Cheney has done as vice president?
Joe Biden: I'm not being a wise guy here ... that I don't know what he's done. I mean, there's not many things I'd pick that I thought he's done that have been good. But I admire his strength. I admire his willingness to take positions that are completely contrary to popular opinion. But I think that what he's done has been just, I don't think Dick Cheney trusts that the American people can make judgments that are in the interest of the country. But the thing I think he's really, really has done: I think he's done more harm than any other single high elected official in memory in terms of shredding the constitution. You know, condoning torture, pushing torture as a policy. This idea of a unitary executive, meaning the Congress and the people have no power in a time of war, and the president controls everything. I don't have any animus toward Dick Cheney but I really do think his attitude about the constitution and the prosecution of this war has been absolutely wrong.
Sarah Palin: Worst thing, I guess that would have been the duck-hunting accident, where you know, that was an accident. And that I think that was made into a caricature of him. And that was kind of unfortunate.
So, the best thing though, he's shown support, along with George W. Bush, of our troops. And I've been there when George Bush has spoken to families of those who have suffered greatly, those who are serving in the military. I've been there when President Bush has embraced those families and expressed the concern and the sympathy speaking for all of America in those times. And for Dick Cheney to have supported that effort of George Bush's. I respect that.
