In 2010, incumbent
State Representative Carl J. Domino could not seek another term due to term limits, instead opting to unsuccessfully run for the
Florida State Senate. Rooney ran to replace him in the 83rd District, which spanned across
Palm Beach County, and encountered Nancy Cardone and Francisco Rodriguez in the
Republican primary, whom he defeated comfortably with 61% of the vote. In the general election, Rooney was opposed by Mark Marciano, the
Democratic nominee and an optometrist. He campaigned on making Florida more business-friendly, specifically supporting efforts to lower the corporate income tax rate and to "streamline the permitting and licensing processes." Ultimately, Rooney defeated Marciano in a landslide, winning over 63% of the vote. When the Florida House districts were redrawn in 2012, Rooney was redistricted into the 85th District, which included most of the territory that he previously represented. He was unopposed in the primary, and in the general election, encountered
Democratic nominee David Lutrin, a physical education teacher. Rooney was endorsed for re-election by the
Palm Beach Post, which suggested that "he could bring a different tone to a Florida House that has been far too ideological" due to his desire for consensus-building, bipartisan legislation. In the end, he was elected over Lutrin by a solid margin, with 58% of the vote. In 2014, Rooney was re-elected to his third term in the legislature unopposed. ==References==
