The primary election is not over.  The outcome is not in as much doubt as the media might like us to think, but there's still plenty of fighting to be done, and if you're going out to canvass for either candidate, more power to you.
In the meantime, however, the DNC is putting together a pretty good sequence of ads that do what we would be doing if we had a nominee.  They define John McCain. 
If we don't do this now -- if we allow McCain (and his MSM admirers) to define his candidacy instead -- our nominee's arguments are going to have to overcome a built-in credibility disadvantage.
So please, whichever candidate you support, do two things:
1) Rec this post.  It's boring as Cream of Wheat, but almost equally good for you.  Apologies if the linebreaks are all screwy.  I'm writing on Safari.
2) Donate to the DNC.http://democrats.org/fundiraqad
I just gave $75, on top of an earlier donation of $75.  It's more than I can afford.  But a McCain victory would be a lot more than I could afford.

TPM reports that big Clinton donors are pressuring Howard Dean to seat delegates from the rule-breaking elections in Florida and Michigan:

In an interview with Election Central, venture capitalist Alan Patricof, a member of Hillary's finance committee and one of the Democratic Party's most influential fundraisers, said that he'd privately urged Dean to do more to get the Florida and Michigan delegations seated -- something that's crucial to the Hillary camp's hopes of closing the gap with Obama.

That such an influential fundraiser is unhappy with the DNC could prove problematic, since the DNC of course relies on such figures to keep the money flowing in.

Obviously, this will annoy people who don't like to see the goalposts moved in the middle of a primary game.
But there are many reasons we should resist this gesture that have nothing to do with the Presidential race.  If you care about down-ticket races, or support Dean's fifty-state strategy, or just don't like to see the Democratic Party pushed around by wealthy donors, today would be a good day to donate to the DNC.  Show Howard we care!
Whatever you contribute, add an extra $.01, so they know it comes from the blogosphere.  They're doing it over at DailyKos too, so you won't be alone.

Who in god's name convinced John McCain to organize last night's speech around the theme of "hope," and then end it this way?          "And my friends, I promise you, I am fired up and ready to go."        I respect the guy, in a wary way, and I was looking forward to a decent general election campaign.  The policy differences with McCain will be visible without Paul Krugman and a microscope.       But if McCain's campaign strategy is to become Barack, and then "dig what we all say" with a lot of air quotes, this thing is just going to be too sad to watch.  Imitation is the sincerest form of flattery, but it's godawful embarrassing politics.  I know Barack has the energy and the new ideas -- but for jeez sakes, John, don't concede that at the start of the game.  You'll spoil the whole thing.

As a rule, primary season is a drag.  Interesting candidates get weeded out early, and by the time the big states roll around, we're left with a choice between the protest vote, the guys who's going to win, Dick Gephardt.
But this primary season has not only failed to suck, it's been downright amazing.  As Greg Sargent keeps telling us, we're going to miss it when it's over.
So how come?  The main reason, of course, is that we've had a bunch of good candidates on the Democratic side, and a wonderful assortment of clowns on the other.
But I'd like to approach this from a narrative, rather than strictly political point of view.  What entities or people (other than the candidates themselves) have done most to forestall primary-season boredom?  Here are my selections:
Mike Huckabee:  I know I'm supposed to be for Mitt, here at TPM.  But fried squirrel, IMHO, matches Mitt's greatest hits, and fundamentally fracturing the Republican coalition puts the Huckster over the top.
New Hampshire:  HRC's surprise victory here set up a enduring pattern of reversals and counter-reversals that has prevented the CW from settling down.  Extra credit to female voters, as well, for flipping a bird at the MSM.  I'm an Obama guy, so I didn't much like it at the time, but I've got to give the people of NH some props. 
Ted Kennedy:  By SC there was some danger that the race would turn into a bitter (and tiresome) battle between genders, races, and generations.  The Kennedy endorsements added a badly needed twist to the narrative.  The candidate of post-racial youth was suddenly also the candidate of boomer sentimentality.  Garry Trudeau has gotten so nostalgic that it's hard to read Doonesbury without misting up.
Egregious underperformers:  On the Democratic side, I'm going to say Nevada.  The big drama here was which union could twist more arms to swing the vote.  Not much fun unless you're in the back rooms doing the twisting, and the final result was irritatingly close to pre-election polling.
On the Republican side, California deserves a lot of blame.  They looked like they were going to go for Mitt, but when the chips were down, they chose boring.
What do you think?  Bracket advocacy as much as you can.  I don't think we're going to swing many undecided votes by doing advocacy on TPM.
