During the campaign, Graber, who had unsuccessfully run for this seat in 1996 and 2008, emphasized his progressive policies, favoring "universal health care and opposition to the wars in Afghanistan and Iraq." Deutch, meanwhile, focused on his "ability to get things done" in the Republican-dominated state legislature and his concern about the national security threat posed by Iran. Former Congressman Wexler, along with then-Congressmen Alcee Hastings, Ron Klein, and Debbie Wasserman Schultz, endorsed Deutch, who ended up winning the primary by a wide margin.
During the campaign, Lynch and Budd each emphasized their commitment to the Tea Party movement, and attacked each other over their business practices and debts. Lynch was attacked for owing the federal government $1.4 million in back income taxes, previously registering to vote as a Democrat, and for owing money to subcontractors. Budd, meanwhile, was attacked for a $25,000 tax lien. By the end of the campaign, Price and Budd announced that they would not support Lynch in the general election if he won the primary. Ultimately, Lynch narrowly won the primary by just 48 votes, narrowly beating out Budd.
The general election campaign featured sharp distinctions between Deutch and Lynch. Lynch attacked the recently-passed Affordable Care Act as a "government takeover" of healthcare, while Deutch said that he would have voted for the bill. McCormick, meanwhile, running as an independent candidate, argued that his lack of affiliation with either of the major parties would allow him to bring change. In the end, owing to the Democratic nature of the district, as well as Deutch's history of representing the area in the legislature, Deutch beat Lynch by a wide margin.
