Indiana ballot access laws, since 1983, have been so restrictive, the Libertarian Party is generally the only party that appears on the ballot for statewide office and Congress. No other party, other than the two major parties, has appeared on the Indiana ballot for a statewide office since 2000, when Pat Buchanan petitioned as the Reform Party nominee.
But the petition requirements for legislature aren’t too restrictive, so in 2012 both the Constitution Party and the Socialist Party placed one or two legislative candidates on the November ballot. The Constitution Party’s nominee, Audrey Queckboerner, polled 8.06% in a race in the 85th district in northeast Indiana. The race also included a Republican and a Democrat.
The Socialist Party ran two legislative nominees, both in the Indianapolis area. In the 39th House district, the state chair of the Socialist Party, John Strinka, polled 9.77% in a two-person race. The Socialist Party, before 2012, had last had legislative candidates on the ballot in Indiana in 1946, and none of the 1946 candidates polled more than .4%. Also in 2012, Socialist Party nominee Ronald Haldeman polled 3.35% in a two-person race against a Democrat. He probably would have done better, but he was running in a black majority district with a black incumbent, and Haldeman is white.
