If you live in a swing state and you're sick of political ads, you haven't seen anything yet. According to Ad Week, a third of the barrage is still to come. Some context: 

More than 915,000 presidential ads have aired on broadcast and national cable through Oct. 21, a 44.5 percent jump from the 637,000 ads that aired in 2008, according to the Wesleyan Media Project.

The Post reported Wednesday that President Obama and his allies are airing more ads than Mitt Romney, even though Republicans are spending more.
