After graduating from law school, Hart began his career in
Houston, Texas before relocating to
Iowa to work at Bradley & Riley, where he specializes in corporate mergers and business law. In the November 2017 Mayoral election, Hart competed against city councilor,
Monica Vernon. As neither candidate earned more than 50 percent of votes cast in the general election, both continued on to a runoff held in December 2017. In the runoff, Hart earned 54.3 percent of votes to Vernon's 45.6 percent. In February 2019, Hart appeared on
C-SPAN to discuss recovery from the
Iowa flood of 2008 and the growing infrastructure crisis in
Iowa. Hart later met with President
Donald Trump to lobby for flood protection. Hart sought reelection to a second term as mayor in 2021. However, in November 2021, he failed to advance to the run-off, finishing only 41 votes behind second-place challenger Amara Andrews. In the subsequent runoff election, Hart endorsed fellow Republican Tiffany O'Donnell. The runoff election was held on November 30, 2021, with O'Donnell overwhelmingly defeating Andrews. ==See also==
