The biggest problem with Kerry is that he was a liberal who campaigned as a moderate, and got caught.
Dean's biggest problem was that he was a moderate who campaigned as a liberal, and was viewed as unelectable.
Lieberman was electable, but in the primaries, folks tend to choose the less moderate candidates. Which is why McCain lost in 2000, and lieberman lost in 2004, yet both would have likely won their respective elctions solidly.
Al Sharpton + Dennis Kucinich -
Edwards was a good VP choice but was not ready for president. Seeemed too inexperienced for me. Good campaigner though.
Gephardt would have made a decent president. Not a very good campaigner.
Clark - electable, and respected by all. Good campaigner. Not a solid platform.
I would have been thoroughly undecided between Dean, Kerry, and Lieberman. I supported Dean up until the overplayed Iowa Scream because of his positions on the Iraq war, and because of his time serving as governor of vermont (he did a great job). I then supported Kerry. Lieberman was always an option but his support of the Iraq War......ya........I didn't like that.
Not like it really mattered. By the time Jersey got to vote only Kerry was on the ballot.
