AINews Summary

The biggest development is the Supreme Court’s decision to block new mail-ballot restrictions, keeping existing voting rules in place for the 2026 elections. Republicans are also pouring money into key Senate races, while a new Iowa poll shows Ashley Hinson ahead by 5 points. The mail-ballot ruling may reduce uncertainty around turnout rules, while heavy GOP spending suggests Republicans are aggressively defending the map. The Iowa poll is a modest positive for Republicans, but the overall Senate picture remains competitive.
