So this is a long article and has a lot of stuff. I picked out a few things that were interesting to note.
The ads have a tendency to stretch the truth. Move-On, one of these 527 groups, ran an ad attacking the Bush administration for cutting education funding and veterans? benefits. Based on President Bush?s latest budget, both education spending and the Veterans Affairs budget would increase by more than 35 percent
It seems some people think this is true

Some stuff on vets as well http://www.washingtonpost.com/ac2/wp-dyn/A4064-2003Jan16
Interesting about the negative ad thing. Kerry pulled an ad that included Mccain at his request.

He also asked moveon to pull a negative ad

Strangely Bush hasn't pulled any ads.
