National and local GOP officials plan to launch a mobile billboard campaign Tuesday targeting Democratic U.S. Reps. Ann Kirkpatrick and Ron Barber for supporting the national health care law.
Kirkpatrick represents a competitive district in northern and eastern Arizona. She served one term in the U.S. House before losing a re-election bid in 2010 to Republican Paul Gosar.
Gosar ran for re-election in a different district in 2012 following redistricting, and Kirkpatrick beat Republican Jonathan Paton in November to return to Congress.
Barber was also elected in November after serving as a former aide to Gabrielle Giffords. Both were wounded in a 2011 mass shooting in Tucson.
