The Supreme Court let Trump's mail-ballot executive order move forward for now, which is bad news for voters who rely on voting by mail ahead of the November midterms.

• Trump's order would have federal agencies build citizenship lists and let the post office refuse to mail ballots to anyone left off them.
• A Boston judge had blocked it, but the Supreme Court paused that block, saying the 23 states suing have not been harmed yet because the order has not been used.
• The court did not rule on whether the order is legal, and warned the decision is preliminary.
• The three liberal justices dissented, arguing the majority ignored the real goal of creating chaos before the election.
• The risk: if lists are handed over close to Election Day, wrongly removed voters may not get ballots in time for courts to fix it.

Outlook: With about 70 days to the midterms, the fight now hinges on whether the administration can actually build and deliver those lists in time — and voters shut out of mail ballots can still vote in person.
