The Missouri Supreme Court heard arguments Thursday on whether a portion of the state’s voter identification law is unconstitutional. 

The law allows three methods to cast a vote. People can show a photo ID; another form of identification, like a utility bill, but are then required to sign an affidavit; or they can cast a provisional ballot, which will only count once they return to show ID or election workers match their signatures with a past ballot.
