Why did Dennis Kucinich run?

[liberal democrat]

During the primary season, I really was not a supporter of any candidate. If I HAD to pick one, I would say Edwards. Anyway, because of that, I did not really follow the primary season all that closely. My question is: What platform did Dennis Kucinich run on and how was it different than Howard's Dean stances on most issues especially the War in Iraq. Do you think the fact that there were several liberal candidates: Carol Moseley Braun, Dennis Kucinich, Sharpton, and Dean, allowed for a hawkish moderate like Kerry be elected as support was scattered between the liberal wing, in terms of both money and manpower?
I am sorry that I am going back to the primaries. But, with Bush away and Congress on vacation, not much political news is going on.
