Martha McSally's TV ad, "Oath."

As I mentioned in this Sunday’s political notebook, three of the four GOP contenders in the CD8 special election primary have TV ads airing. Here are links to the spots, which are each 30 seconds long:

• Martha McSally has two different ads: "Oath" and "Born A Warrior."

• Jesse Kelly has one ad: "Jesse Kelly for Congress."

• Dave Sitton has one ad: "Leadership for our community."

The fourth candidate, Frank Antenori, does not have a TV ad, but had a radio ad: "We are not victims."

The clock is ticking down for the four in this condensed election cycle. Early ballots went out Thursday. The primary is on April 17. At 7 p.m. Monday, March 26, they square off yet again in a candidate debate at Canyon Del Oro High School hosted by the Pima County Young Republicans.

Though the four agree on most issues, there are contrasts between them, as I wrote about in this Sunday story. You can also click here to compare how the four propose to address four key issues: jobs and the economy; border security; Social Security; and the debt.
