Tucson, Arizona (CNN) – Voters in Arizona's 8th Congressional District will decide Tuesday who will serve out the remainder of former Rep. Gabrielle Giffords' term in a race seen by politicos as a test for the fall and by observers as taking the temperature of the nation's political discourse.
On one side is Giffords' aide Ron Barber, who was wounded in the 2011 shooting that critically injured Giffords and killed six other people. His opponent is Republican Jesse Kelly, a former Marine and Iraq war veteran who ran a tea party-fueled campaign against Giffords in 2010 that came up 4,000 votes short.
Tucson, Arizona (CNN) – Former Democratic Congresswoman Gabrielle Giffords made a rare appearance before a cheering crowd of supporters at a "Get out the vote" concert in downtown Tucson.
Giffords was joined by her husband, Mark Kelly, at the Saturday event for a special election race for the seat from which she resigned.
