I was surprised that Al Gore did not run again in 2004. As a former Vice President, Southerner, and winner of the popular vote in 2000, he would have had a reasonable and legitimate claim to the right to fight again for the ultimate title.
On the other hand, John Kerry -- the Senator from Massachusetts who lost the popular vote by 3 million votes to a largely unpopular sitting President -- doesn't deserve a second chance. But as the Boston Herald notes, that doesn't meant that he isn't going to try.
One thing will be interesting -- to watch how Kerry and Edwards go after each other in the battle for the nomination.
