A federal judge ruled Monday that Louisiana lawmakers‘ attempt to move the state‘s congressional primary elections up to October was unconstitutional.
At issue is Louisiana‘s unique "open primary" system of elections in which all candidates run in one election regardless of party affiliation. It is possible for a candidate to win outright in the primary election if that candidate receives more than half of the votes.
