Giffords herself has drawn the ire of the right, especially for her support of the health care bill from politicians like Sarah Palin.
Her Tucson office was vandalized a few hours after the House vote to approve the health care law in March, with someone either kicking or shooting out a glass door and window.
Despite the animosity she has generated from the right, Giffords describes herself as a former Republican and current Blue Dog Democrat.
“You know, actually as a former Republican, you know, I consider myself someone who is pretty in the middle, I’m a blue dog Democrat, and one that is interested in making sure that our country maintains our prosperity and frankly, our superiority over other countries and that’s where we look at these threat, obviously our defense budget, our level of education,” she said in an interview with Fox this week.
