That, and other news, in today’s Political Panorama.

Barack Obama’s 30-minute infomercial tonight would seem like a slam dunk. If you have the money to make such a massive buy to make a closing argument, do it. Candidates used to do it all the time before the cost of network prime time went through the roof.

But is it such a wise idea? Elisabeth Hasselbeck, campaigning for McCain-Palin, called the purchase obscene, but that is what you would expect from an opposing campaign with far fewer resources. They are trying to make an issue out of the outlay at a time when Americans are losing their jobs and watching their retirement savings disappear. Nevertheless, a lot depends on the tone Obama takes tonight, and whether he comes across in any way presumptuous. Republicans have hit him before for his speech before massive crowds in Berlin and his nomination address before Greek columns, so I would expect there will be some suggestions that Obama is acting as if he already has it in the bag. In truth, the campaign is cautious as ever, and it would surprise me if, for instance, Obama appears in a setting that looks like the Oval Office.

Republican political strategist Alex Castrellanos tells the Politico, “It’s like football. People may complain that a team is running up the score, but that team is still the one that wins.”

The biggest risk, the Politico notes, is that it will anger people who find their favorite program is pre-empted.

The last candidate to buy a similar allotment of time was Ross Perot.

The campaign provided a “trailer” to the New York Times, with footage of Americana from director David Guggenheim.

Update: McCain’s response to Obama’s 30 minutes does invoke the big crowds and Denver convention:

GOTV: Leonardo DiCaprio organizes a bevy of new stars for a new get out the vote video. Tom Cruise, Cameron Diaz, Leonardo DiCaprio, Snoop Dogg, Harrison Ford, Julia Roberts, Ben Stiller, Will Smith, Steven Spielberg and Justin Timberlake appear in the new PSA, produced by DiCaprio’s Appian Way Prods. The first video, introduced on Oct. 1, was responsible for some 300,000 new voters registered, according to DiCaprio’s rep.

Prop.8 & Parenting: Melissa Etheridge writes on The Daily Beast about her family and Proposition 8: “The proponents of it have run the most fearful of television ads telling the people that if this doesn’t pass they will have to teach about homos to small grade school children. I can’t seem to recall any relationships ever being taught in school and I can’t find anything about that in this proposition. Now, I know my preference of life mate freaks some people out. Maybe it is just their fear of sex or intimacy. I know that they hold up the bible and say that it’s wrong. Fine, let me stand before my creator and take any consequences there might be to living my life in truth and balance with my spirit.”

Joe the Plummer’s Deal: Jeffrey Ressner of the Politico reports the not-too-surprising news that Joe Wurzelbacher, aka “Joe the Plummer,” is persuing a deal for a record deal. Ressner writes, “On Tuesday, Wurzelbacher joined country music artist and producer Aaron Tippin to form a new partnership that includes booking-management firm Bobby Roberts and publicity-management concern The Press Office to field the multiple media offers he’s received over the past few weeks.” Tippin and Wurzelbacher met last weekend on the set of Mike Huckabee’s Fox show.
