The race was one of the most competitive in the state. Late in the campaign, Hayworth released a campaign ad featuring her gay son, who told voters that his mother was "not an extremist." The ad drew criticism from LGBT groups, who said that Hayworth did not do enough to support pro-LGBT legislation while in office.

She added that any additions to the disaster relief fund must be offset by federal budget cuts elsewhere.
Hayworth voted for Paul Ryan's budget in 2011 and 2012. During an interview on Early Start on CNN, she reiterated her support for Ryan, calling him a "teacher and mentor" for the House Republicans when it comes to "a budget plan that actually will work for the United States." In 2011, she was one of several House Republicans who sent a letter to President Obama urging him to expedite the permitting process for safe offshore energy exploration.
