AINews Summary
Republican officials are backing a Supreme Court fight over new mail-voting rules, and GOP events are leaning hard into Trump to boost turnout and fundraising. Separate coverage says Democrats are widening their Senate map, pointing to a more competitive national race environment. The South Dakota market itself gets little direct new information. The news is mostly about the wider Senate environment, not South Dakota specifically. It suggests a more competitive national backdrop, but it does not clearly shift this South Dakota party market yet.
