Katie Couric's Notebook: Campaign Ads

Research shows 60 percent of political commercials aired in the last 30 days have been negative. And when you look at ads run by outside groups, the number is nearly 90 percent.

As part of our series "American Voices", I spoke with a group of Independent voters in Pennsylvania who said with all the problems the country is facing, they are looking for solutions, not trash talking.

A Supreme Court ruling earlier this year helped open the floodgates for a torrent of donations to outside groups that don't have to disclose their donors or agendas. Perhaps that money would be better spent on spots dissecting the issues with truth in advertising about what the candidates are selling. Otherwise, the voters I spoke with say they'll have no idea what they're really buying on November 2nd.

That's a page from my notebook.
