Hans von Spakovsky writes on the shameful disenfranchisement of military voters in NY-20:

In New York, ten counties make up the 20th congressional district, and nine of them sent their absentee ballots to overseas voters too late for them to be received and returned in time to count in this election. One county mailed them on March 12 and eight counties mailed them on March 13, all by regular mail with only one exception - Essex County used an express mail service. Under New York law, absentee ballots in this race had to be postmarked by March 30, the day before the March 31 election, and received by April 7. That left most military voters only 25 days to receive, mark and return their absentee ballots, which everyone agrees isn't enough time, given overseas mail delays. The Civil Rights Division of the Department of Justice, which is responsible for enforcing the federal statute that guarantees the right of overseas citizens and military personnel to vote by absentee ballot, contacted the New York State Board of Elections and requested that they issue their ballots sooner for this race. The two Republican members of the board voted to support this request. Yet the two Democratic members of the board, shamefully enough, voted against doing so. Were they trying to disenfranchise military voters?
