On August 6, John Schmitz, an independent candidate for Mayor of Indianapolis, sued to obtain a place on the ballot. Schmitz v Marion County Board of Elections, s.d., 1:19cv-3314. He needed 6,106 valid signatures. He submitted 8,295. The Board rejected his petition. He would have had enough valid signatures, except that election officials disallowed the signatures of people who are clearly registered voters in Indianapolis, but who listed a different address on the petition than on their voter registration form. UPDATE: see this news story.
Here is the Complaint, which cites several federal laws about voting, including the 1965 Voting Rights Act which has often been interpreted to mean that if an elections administrator knows that a particular signer is a registered voter within the relevant jurisdiction, the signature counts even if the address on the petition doesn’t match the address on the voter registration form. The case is assigned to U.S. District Court Judge Tanya Walton Pratt, an Obama appointee.
