Who are my U.S. senators in Wisconsin?
Wisconsin's two U.S. senators are: Ron Johnson (Republican) — serving since Jan. 3, 2011 GovTrack.us Congress.gov Tammy Baldwin (Democrat) — serving since January 2013 Both are currently in office. Note that Wisconsin has a Senate election happening in 2026, though that involves the state Senate, not the U.S. Senate seats — Wisconsin's two U.S. Senate seats aren't up this cycle.

The response correctly identifies both U.S. senators from Wisconsin: Tammy Baldwin and Ron Johnson, matching the ground truth. The claim about a 2026 Wisconsin Senate election being state-level is a minor added confusion but does not undermine the correct core answer.
