In the latest polling, according to CNNPolitics.com, Edwards leads Democratic candidates in Iowa with 27%, followed by Clinton with 22% and Obama with 16%.

Clinton and Giuliani are the likely winners of their respective party primaries, according to the usually accurate Iowa Electronics Markets, which is run by professors at the University of Iowa and lets people trade and sell in candidate "stock" using real money (limited to $500 per trader).

While the Clinton campaign tries to be careful not to appear as if it has the nomination sewn up, many of the Republican candidates for president seem to think it does, or at least they are choosing to act that way, judging by the number of times Hillary Clinton was mentioned during the GOP debate in Orlando last night.

In case you missed it, Al Gore won a Nobel Peace Prize. He is still not running for president. But that doesn't mean there isn't lots of speculation about whether or not he will.
