Smith was first elected to represent the 72nd district (part of
Richland County) in the
South Carolina House of Representatives in 1996. Smith was a favorite to run for
Governor of South Carolina in
2010, before
Vincent Sheheen entered. Sheheen subsequently lost to Republican nominee
Nikki Haley in the general election. Smith was reportedly urged to run for governor by Joe Biden in April and then again in September. He appeared at the
Chapin Labor Day Parade in early September, further stoking speculation that he would run for governor. Smith announced his candidacy on October 5, 2017, becoming the first Democrat in a race that already had four Republican candidates. In an interview shortly after Smith announced his candidacy, Biden spoke of Smith, saying "...this is a guy, I swear to God, that I would trust with anything. This is a guy who I watched, he never puts himself before anybody else." He described Smith and his late son
Beau Biden as "kindred spirits". On November 6, 2018, Smith was defeated by incumbent governor
Henry McMaster. Smith held 46% of the popular vote to McMaster's 54%. ==Military service==
