The Democratic-aligned House Majority PAC is placing a $340,000 television ad buy in Arizona’s 8th district special election to replace former Rep. Gabrielle Giffords (D).

The three-week buy is set to begin running Friday on broadcast and cable in Tucson, and targets Republican nominee Jesse Kelly, who faces former Giffords aide Ron Barber. The buy is intended to supplement a two week ad buy placed by the Democratic Congressional Campaign Committee, which is due to expire the same day the House Majority PAC TV spot hits the airwaves.

“Jesse Kelly may be trying to pull the wool over the eyes of voters, but the House Majority PAC ad will remind Arizonans of just how extreme Jesse Kelly is — using his own words,” said Andy Stone, a spokesman for the political action committee.

House Majority PAC is a super PAC that was formed to help Democrats win back the House. The organization was unable to make a script or video of the ad available. Kelly was the 8th district GOP nominee in 2010. Roll Call rates this race as a Tossup. The special election is June 12.
