Beginning today and continuing through Election Day, Roll Call will offer a daily smattering of campaign ads that the Politics Team finds worthy of highlighting. Look for the Daily Ad Tracker most week-day afternoons.

Today’s offering features a collection of television spots launched in House and Senate races and run by candidate’s campaigns, national party committees and third party groups, such as super PACS. The theme of today’s Tracker: “Firsts.”

Arizona Senate: Rep. Jeff Flake (R) is up with his first television ad of the general election campaign for the Grand Canyon State’s open Senate seat. In the first seconds of the ad, he seeks to tie his Democratic opponent, former Surgeon General Richard Carmona, to President Barack Obama. The ad is set to air in the Phoenix and Tucson media markets. https://www.youtube.com/watch?v=Wau6Z_SKzI8&feature=youtu.be
