Donnelly touts votes with Republicans in appeal to center

The ad is running statewide on broadcast and cable.

The ad is the latest in a series from Donnelly that portrays him as a centrist deal-maker and Mourdock as a hard-line conservative, and the message seems to be working: Polls have shown the two candidates neck and neck, and national groups on both sides are pouring money into the state. The Hill rates the race a "toss-up."
