First, other than Gore, he's an incredible statesman and he's responsible for many of the wins in 06. Before Webb won the primary and before any other Democrat supported Webb, Kerry was out there supporting him and helping him fundraise. Without that initial support, Webb would not have made it past the primary.
Then there's Joe Sestak. He was getting swiftied by the opposition party. But Kerry held press conference after press conference with him. He travelled the state giving speaches for him and fundraising for him. Here's the long list of candidates who he helped. It's longer than even John Edwards who ran second to Kerry and he has the most wins as well.

And yet Senator Kerry wasn't even on the Judicial committee but because nobody there was willing to risk their name, he ran the filibuster. Now, I personally am fairly 'undecided' about the wedge issue abortion, but I am against everything else Alito stood for--corporatism, strip searches of minors, etc...Even though the filibuster eventually lost, it was a tremendous boost to the power and respect that the netroots achieved.
And on issues like national security and handling the Iraq mess--Kerry was spot on correct in 04. He was right in 04 about Bush trying to dismantle social security. He was right about the environment and about healthcare. He was right about taxes and the economy and jobs.
Kerry may be battle-worn from 04, but the guy is skinnier, sharper, and much more prepared to duke-it-out with the right-winged smear machine.
He and Gore and Edwards are the only ones who have the battlescars to return to the ring with a tougher mindset. And even though Hillary Clinton is battlescarred too, she unfortunately has a few more major 'negatives' (rightly or wrongly) such as being married to Bill, being a woman, and being loathed by people who don't even want to learn more about what she has done.
Regardless--the Democratic field is rich with potential! All of us should be so proud because I believe it's our hard work that convinced them that our causes were worth fighting for. We can finally point to liberalism as a good thing instead of the smear that it was two years before. For that, we owe Bush and the Republicans a huge thank you.
And my hope on DU is to see us use our activism to spread the truth about the Republican candidates and the Republican agenda, instead of trying to take down the opponents of 'our favorite' in 08. We are here in 06. The top headlines are the war, torture, hearings, and the firing of prosecutors. We can not take our eyes off the current legislative process and bicker about 08.
The Republicans never rest or take their eyes off the prize, nor should we. The prize is a Democratic controlled house and Senate. And maybe just maybe if we work hard enough, we can get a few Republicans to vote with Democrats frequently enough to take away Lieberman's pathetic version of neo-conservatism-independent-Democrat-Republican slime.
