The U.S. Senate expects to vote on S.1390 on Tuesday, October 20. This is the Defense Authorization Bill, and it includes the Military and Overseas Voter Empowerment Act. It requires states to mail absentee ballots (in federal elections) to overseas absentee voters no later than 45 days before the general election. Assuming the bill is signed into law, it will almost certainly require the states that now use September primaries to move them to August or an earlier month.

The bill passed the Senate once already, but it needs another Senate vote because it has had amendments made since the first Senate vote.
