Supreme Court voting mailin ballots Republican.

The Supreme Court is reviving a Republican challenge to a law allowing the counting of late-arriving mail ballots, a target of President Donald Trump. The high court found Wednesday that an Illinois congressman has the legal right to challenge the law even though late-arriving ballots likely had little effect on the race he won easily. The state had argued that allowing the lawsuit by Rep. Mike Bost of Illinois would open the floodgates for more election litigation. Bost argued that vote-total considerations shouldn’t affect his ability to come to court, and a majority of the justices agreed.
