Corporations are already formed for the sole purpose of electing an individual aka. The Committee to Elect Barack Obama.<p>Also, buying all the airtime is basically impossible as it decreases supply while increasing demand. Once investors realized someone was trying to do that, they'd buy ad space just to sell to that company. It would be incredibly expensive to organize all the sub-companies needed to buy it all with out anyone noticing. If anyone notices the gig is up as investors will swoop in to take a cut of the action.<p>Besides, if anyone actually managed to do that, it would be VERY easy for the other side to get articles written about how their viewpoints can't be expressed.<p>It would generate so much free publicity for the other campaign that it would likely be counterproductive. I'd love to be the candidate opposing the guy who bought all the ad time. It's pretty much a guaranteed victory because of the public backlash that would result.
