(AP) — A state Senate candidate wants to challenge an Indiana law that prevents him from appearing on the November ballot as the nominee of two political parties. The lawsuit was filed after Marion County election officials restricted a man to one party affiliation after he won both the Republican and Libertarian nominations for a township board seat. Arthus said he will act as his own attorney and intends to file a lawsuit in federal court as soon as the Indiana Election Division takes action to drop his Libertarian Party line from the ballot.
