Blue Dog Rep. Gabrielle Giffords (D) announced that she raised almost $591,000 for her re-election campaign, bringing her to more than $2.2 million in cash on hand.

Her support for health care reform drew several Republicans into the Aug. 24 primary.

A spokesman for Jesse Kelly (R) said his campaign raised $120,000 in the second quarter, its best to date.

Former state Sen. Jonathan Paton (R) had more than $400,000 on hand at the end of the first quarter but did not yet have second-quarter numbers available.

Paton spokesman Daniel Scarpinato said his campaign doesn’t expect to match the incumbent. “We’re never going to be able to match her in terms of how much money she’ll have because she’s better at shaking the D.C. money tree than anyone else we’ve seen in Arizona in years,” he said.

Brian Miller, who served in the Air Force Reserve in Afghanistan, also will be on the primary ballot. Iraq War veteran Andy Goss dropped out and endorsed Kelly last week.
