I'm starting a Biden use of the word "literally" count. So far he's at 3, and he's only been talking for five minutes.
Here's James Fallows' take on Biden in the Senate. That is exactly how he would "ask questions" - talk for twenty minutes, then say, "can you comment on that?" Fallows thinks that Biden's ego could be a plus.
I will give that Biden is a heck of a politician and won't take anything sitting down, which is perhaps what Obama needs right now. But that doesn't mean I have to like him. And I still don't think it was a great decision on Obama's part.
