Former Giffords Aide Running to Serve Last Six Months of Her Term

TUCSON, AZ - JANUARY 8: U.S. Rep. Gabrielle Giffords (D-AZ) smiles during the "Remembering January 8th Candlelight Vigil" held at the University of Arizona Mall January 8, 2012 in Tucson, Arizona. The event was the culmination of several days commemorating the one year anniversary of a shooting rampage that killed six people and wounded more than a dozen more.

Sixty-six-year-old Democrat Ron Barber already has Gabby Giffords's and husband Mark Kelly's endorsement in the interim election for a replacement to serve the rest of the congresswoman's term. Giffords resigned late last month to focus on her recovery; Barber was also injured during the January 8, 2011 attack outside a Safeway in Tuscon, Arizona. But the self-described non-politician isn't sure if he would run for a full term if he wins. He'd have six months to decide if he wants to dabble in that kind of futility.
