What to know about mail-in voting and Trump’s order : NPR

Key Points:

• The Trump administration has requested the Supreme Court to lift a federal judge's temporary restraining order blocking key parts of the USPS plan aimed at restricting mail-in voting for the midterm elections.
• Currently, mail-in voting remains available as usual, with USPS expected to deliver ballots, since the court order prevents enforcement of the new USPS requirements for states to provide voter lists and barcoded envelopes.
• The USPS plan would require states to submit mail-in voter information and use specific barcodes on ballot envelopes, with USPS potentially refusing to deliver ballots that don't meet these criteria.
• Election experts warn it is likely too late for USPS to implement the plan without causing significant disruptions, citing a whistleblower report about untested systems and policies that could delay or prevent ballot delivery.
• Legal challenges argue USPS lacks authority to regulate voting procedures, while the Trump administration defends the plan as a measure to prevent illegal voting, despite evidence showing such fraud to be extremely rare; the Supreme Court has not yet ruled on the plan's legality.
