kerryvilsack.com, kerryvilsack.org, kerryvilsack04.com, kerryvilsack04.org are all registered to the same person, presumably a Kerry functionary. For sites for the other candidates (incl. Hillary) the name's already been squatted upon. I think it'll be Vilsack.
Vilsack has done what no other RAT was able to do in Iowa in thirty years: win and hold the governorship.
Though he is an extreme leftwinger, he has been successful in maintaining a fairly moderate image, helped by the fact that he has had to govern with the GOP in control of both houses of the legislature.
He was counted out in his first election. His opponent was far ahead in the polls. But he made an impressive run at the end and won. His political skills should not be underestimated.
But he does have some vulnerabilities. He was busted by the press early on for issuing a secret executive order giving preferential hiring treatment to gays, lesbians, transgenders, etc.
Congressman Steve King, then a state senator, sued him over that and won.
