If I could just build on what BJ said (repeat what he said +)
It is a pretty *%$# pathetic situation, if you are a democrat, and just spent 4 years waiting for the opportunity to displace Bush, and then the only thing that the Dem. Party can come up with is Kerry. If you think about it that way, you can see how one may be in a quandry. To place your vote, you basically, have to overcome the emotional barrier of either voting for Kerry, or renigging on four years of waiting and hoping. :-(
