When incumbent State Representative Fred Brummer was unable to seek another term in the legislature and instead opted to run for the Orange County Commission, Nelson ran to succeed him in the 38th District, which was based in northern
Orange County, stretching from
Apopka to
Ocoee,
Orlando, and
Maitland. He won the
Republican primary and the general election entirely uncontested. In 2008, he faced his first opponents: Lonnie Thompson, the
Democratic nominee, and Lawrence Fisher, an
independent candidate. The
Orlando Sentinel endorsed Thompson over Nelson, observing, "[H]e better appreciates the important issues facing the district than does his opponent," and criticizing Nelson for not protecting the
Wekiva River and for not supporting property-insurance reforms. Despite this fact, Nelson won his second term over Thompson by a solid margin of victory, winning 54% of the vote to Thompson's 43% and Fisher's 3%. When Nelson ran for a third term in 2010, he did not face a Democratic opponent, but instead a member of the
Florida Tea Party, James Heinzelman. Nelson ran on a platform of "repealing parts of SB 550, which would impose a five-year inspection schedule on septic tanks," which he said would lead to a "bureaucratic and costly nightmare" and on supporting
SunRail, which Heinzeilman vocally opposed. Ultimately, Heinzelman did not prove to be a significant challenge for Nelson, and he won re-election with 82% of the vote. In 2012, when the legislative districts were redrawn, Nelson was moved into the 31st District, which, like his previous district, was based in
Apopka, but unlike his previous district, stretched into northern
Lake County and won re-election to his fourth term entirely unopposed. ==Orange County Commission==
