Arizona’s 2nd Congressional District is now an open seat, with Rep. Martha McSally’s official decision to run for the U.S. Senate.

CD2 is considered a swing district, and the Cook Political Report, which follows congressional races across the country, now has it leaning Democratic.

With me to gauge the district and the candidates running to succeed McSally is Jim Nintzel, executive editor of Tucson Weekly and Tucson Local Media.
