美国民主党在多个州的初选投票率创下数十年来的新高。威斯康星州民主党初选投票接近80万人，为20多年来最高水平[1]，密歇根州超过150万人投票，创造了该州中期选举的新纪录[1]。相比注册选民人数，威斯康星州民主党投票占比达22%，密歇根州超过18%[1]。
在其他关键州，得克萨斯州民主党参议员初选吸引约230万人投票，占注册选民的12%；格鲁吉亚州民主党参与者超过100万人，占比13%[1]。
民主党方面对这一高投票率表示乐观，认为可能预示11月中期选举前景良好。然而，分析人士指出，初选投票率并非可靠的大选预测指标[1]。
在参议院席位竞争方面，共和党目前控制53-47的多数，民主党需要获得4个席位才能获得参议院多数[1]。密歇根州民主党参议员初选的竞争格外激烈，相关支出超过8000万美元[1]。
Democratic primary voting has reached record highs in several key states, raising hopes among party strategists about momentum heading into the general election. Wisconsin recorded nearly 800,000 Democratic primary voters, the highest turnout in more than two decades [1], while Michigan exceeded 1.5 million votes, setting a midterm election record for the state [1]. In Texas, approximately 2.3 million Democrats cast votes in the Senate primary, representing 12 percent of registered voters, and Georgia saw turnout exceed 1 million, accounting for 13 percent of its registered electorate [1]. Michigan's Democratic primary participation reached over 18 percent of registered voters, compared to Wisconsin's 22 percent [1].
Democrats have expressed optimism that these elevated turnout figures could signal favorable prospects for November's midterm elections [1]. However, political analysts caution that primary voting rates do not reliably predict general election outcomes. The Republican Party currently maintains a Senate majority of 53-47, meaning Democrats would need to gain four seats to achieve control [1]. Campaign spending in Michigan's Democratic Senate primary exceeded $80 million [1], underscoring the competitive stakes in these contests.
