2025年12月31日,爱荷华州参议院第16区举行了特别选举,民主党Renee Hardman以大约52%的选票击败了共和党Brad H. Johnson。 On December 31, 2025, a special election was held in Iowa's Senate District 16, and Democrat Renee Hardman defeated Republican Brad H. Johnson with roughly 52% of the vote. 在一个共和党占多数的州,在一个历史上由共和党统治的州的胜利代表了罕见的民主胜利,使共和党无法在由50名成员组成的参议院中重新获得超级多数席位。 In a state where Republicans predominate, the victory in a historically Republican-leaning district represents a rare Democratic victory and keeps the GOP from regaining a supermajority in the 50-member Senate. 在2026年选举之前,投票率很高,这凸显了种族的重要性。 早期投票和年轻选民及郊区选民的更多参与都推动了投票率的提高。 The race's importance as a bellwether ahead of the 2026 elections was highlighted by the high turnout, which was fueled by early voting and increased participation from younger and suburban voters.
