So far, Richard Mourdock has gotten the help of Karl Rove's PAC in his fight against Joe Donnelly.
On Monday, Donnelly released an ad that signifies, I believe, his first counter attack in the air war. This 30-second ad seeks to define Mourdock and tries to draw a contrast between the Republican nominee and Donnelly.
The ad comes after an excellent Democratic debate that showed Donnelly working hard for the support of the Democratic base. I think this race will be a tight one, and that benefits Donnelly. Don't forget, he ran a tight race for reelection and bucked the Republican tied in 2010 to beat Jackie Walorski by just a hair.
