Ad Age’s Evan Tracey lays out the case for running a campaign ad on the Super Bowl, starting with the fact that it comes soon before Feb. 5 and the new super primary day:

Let us say that an ad in the big game costs between $2 million and $3 million. It’s expensive, sure. But the media exposure is bound to be worth at least another $20 million. Furthermore, for the sake of argument, let’s suppose the teams in the big game hailed from Feb. 5 states such as California and Florida. Then you would have an even larger audience in those delegate-rich states. Finally, the top-tier campaigns are likely to have plenty of money in the bank. And in politics, it’s use it or lose it, because there is no second quarter in which to recover.

Common sense tells me there is only an ever-so-slight possibility, and it’s likely such an ad purchase would be unworkable. But it does highlight the bona fide challenge ahead for the presidential campaigns in the constantly compacting political calendar.

The possibilities are endless: Talking frogs for Giuliani. Hillary swigging Bud. The GoDaddy girl endorses Romney. . . .
