Pay close attention: It's all about Ohio. Whoever wins Ohio wins the election. Kerry knows this. So does Bush. If you live on Ohio, I imagine every ad is a political ad and if not, it soon will be.
All this post-convention "bounce" they talk about ultimately means nothing if Bush loses Ohio because it's not the popular vote that matters, as Gore discovered. It's all about the electoral college and if Kerry can win Ohio, it's all over for Bush.
