A recent decision has paved the way for potential changes to mail-in voting. President Donald Trump's executive order may be implemented, although the extent of its impact before the midterm elections is uncertain. Other court challenges are possible, which could slow the order's implementation.

The U.S. Postal Service has outlined its plan to carry out the order, but time is limited to make significant changes. Some states will soon send out ballots, starting with overseas and military voters.

Further details about the decision and its potential effects are available, including the ruling that certain states lacked the legal right to challenge the order.
