Who Else Besides Joe Biden Might Crash The Debate?

This week, from the Wynn Las Vegas Casino Hotel, CNN will televise the first Democratic debate of the primary season. The news channel's guru, Jeff Zucker, has a problem here: Unlike the fractious, bumptious, eminently televisable Republican mess that garnered huge ratings for the network, the Democratic debate features two front-runners who won't fight one another, along with a handful of little-known candidates whose first priority is make the sort of generically good impression that could propel them to the mid-single digits in the polls.

But you need some spice on the Strip. So where is it? Where's the zazz? Well, Zucker -- who's more of a showman than a newsman -- has hit upon an interesting idea. Rather than set strict candidate criteria that would exclude participants, he's created something of an open-door policy for the debate, hoping to include even more contenders.

Now, of course, we all know why CNN has created this policy: There's one potential candidate, lingering right at the edge of jumping into the race, whom they'd dearly love to have behind a lectern reserved especially for him.

But this is Vegas, kids. You never know who might stumble in off the Strip to roll the dice. On this week's First To Last, we rate eight special guests who could crash CNN's party.
