USPS to eliminate Saturday delivery, what will be the impact on voting by mail?

Reports out this morning indicate that the USPS is planning on eliminating Saturday postal delivery.

This has important implications for the increasing tendency of states to expand opportunities for voting by mail. The elimination of Saturday delivery will mean that there will effectively be fewer days for people to receive their ballots pre-election, and for voters to easily return their voted ballots. States may need to make the pre-election voting by mail period longer, to develop opportunities for voters to drop off voted ballots pre-election in a secure and easy way, and to educate voters about the importance of mailing ballots well before deadlines.
