As Orrin Judd writes, "As tough is this ad is, consider how much information they have to provide you before they tie the whole message together. It takes twenty seconds longer than the voter's attention span...That said, it's like crack for us wonks."

And the left is reeling from the overdose; witness Michael Crowley of The New Republic's meltdown:

You thought Corsi was swift boating? This is swift boating. The 9/11 link is completely and utterly revolting.

Except that it's true on multiple levels: true in the actual definition of "Swift Boating", as opposed to the pejorative that the media want to think it is, and true in that Obama has to be comfortable on some level with domestic terrorism simply to be buds with Ayers, whose Radical Chic salad days not coincidentally occurred near-simultaneously with John Kerry's Winter Soldier phase. And as Allahpundit notes:

All of this punctuated, of course, but a reminder of how decidedly un-despicable the left would an ad along these lines targeting a conservative who was palsy walsy with an abortion bomber.

Of course, the timing is interesting: the Swift Vets waited until after the convention in 2004, and performed political jujitsu by using Kerry's "Reporting For Duty" speech against him; McCain is launching his pincer movement days before the convention--even before Obama has nominated his veep, which has got to be driving The One to bitter distraction--and hopefully, his colleagues in the Obamedia will all overreact as badly as Michael Crowley did above, thus writing McCain's next ad.

Preseason's officially over. As someone who's name rhymes with the GOP candidate once said, welcome to the party, pal.

Update: A correction--as Newsday notes, the above video wasn't from John McCain's campaign but the American Issues Project:

A conservative nonprofit group with a past link to Sen. John McCain's presidential campaign wants to spend $2.8 million on an ad questioning Democrat Barack Obama's relationship to a founder of the 1960s radical group Weather Underground.

The ad, which is expected to begin airing Thursday in Michigan and Friday in Ohio, focuses on William Ayers, whose Weatherman organization took credit for a series of bombings, including nonfatal explosions at the Pentagon and U.S. Capitol four decades ago.

American Issues Project, the sponsor of the ad, is a nonprofit 501(c)4 organization. One of its board members, Ed Failor Jr., was a paid consultant for McCain's campaign in Iowa last year. The campaign paid his firm $50,000 until July 2007. American Issues Project spokesman Christian Pinkston said Failor has no connection to the McCain campaign now.

The ad signals the emergence of the type of tough advertising by independent organizations that operate outside the financial limits of campaign finance law. It is reminiscent of the Swift Boat ads aired against John Kerry four years ago questioning his military service and are widely blamed by Democrats for contributing to his defeat.

Organizers sought to air the ad on Fox News Channel, but a Fox spokesman said the network declined to run it. He would not say why.

All is proceeding according to plan.
