The remaining 16 states will hold their contests between August 6 and September 10.1 149 states will have held a primary. Louisiana has a unique system, with no nominees determined prior to a November 5 all-party primary. A candidate can win an election that day by getting a majority of the vote, otherwise there is a top two runoff.
