After being convicted on federal charges of making threatening and obscene phone calls to his wife, Landham spent three years in prison. However the U.S. Sixth Circuit Court of Appeals reversed the conviction in May 2001.
In 2003, Landham ran in the Republican Party primary election for the post of Governor of Kentucky, hoping to repeat the success of his Predator castmates Minnesota Governor Jesse Ventura and California Governor Arnold Schwarzenegger. He based his candidacy on opposition to an amendment which endorsed the Kentucky Family Court, saying his bad experiences at the hands of the family court had convinced him it was for the benefit of lawyers rather than families or children. He was unsuccessful in gaining the party's nomination. He ran briefly as an independent candidate, but withdrew on June 18, 2003, and endorsed the Republican slate.
In January 2004, Landham announced his candidacy for the 27th State Senate District of Kentucky. In 2005, Landham spoke at a Council of Conservative Citizens (CofCC) convention. Landham has also appeared on the CofCC-affiliated radio show, The Political Cesspool.
On September 19, 2006, Landham was injured in a four-car accident in Ashland, Kentucky.
On June 25, 2008, Landham announced his candidacy for the U.S. Senate seat held by Mitch McConnell on the Libertarian line. The same day Landham was accused of calling for genocide against Arabs (whom Landham referred to as "camel dung shovelers," "camel jockeys," and "rag-heads") for his comments on the political radio show The Weekly Filibuster. Three days later, on June 28, the Kentucky Libertarians voted unanimously to withdraw Landham's nomination, citing his comments were not in keeping with the party's platform and values.
Landham died on August 17, 2017, aged 76, from congestive heart failure.
