Cheney did great. One thing I wish he would have done was debunk the urban legend that Bush "let" bin Landen go at Tora Bora and that we "outsourced" the job.
The format did not lend itself to addressing all of the lies, misstatement of facts, charges etc made by Edwards. It just wasn't possible given the laundry list of items spouted by Edwards. Cheney should have asked for more time, but the one time he did, it was turned down.
