So, clearly, John Edwards does not understand how odds work. Despite my bold 2:1 prediction of a few hours ago, Edwards chose not to use his Daily Show appearance to announce his candidacy for '08. Instead, he took the "thinly-veiled acknowledgment" approach:

Stewart: "Do you feel like going back into politics would diminish your effectiveness, or enhance it?"
Edwards: "Depends on what the job is."

Also, in response to a question about announcements, he "announced" that people should keep an eye on his website in the coming weeks. So I guess that's something. But come on, John: did you hear the silence that fell over that crowd when you said you had something to announce? Those people were ready for some serious supportive cheering. You should have taken the plunge.
