Wisconsin, a key swing state in the United States, will vote Tuesday for a new state Supreme Court justice, with Democratic-backed Justice Susan Crawford facing off against Trump-backed Brad Schimel. The election has a high stake for Trump and Musk. A Schimel win would tilt the court to the conservative side, with national implications for abortion rights, congressional gerrymandering and the future of voting laws, and could affect the state's 2026 midterm and 2028 general elections. Political analysts widely see the election as an early test of how voters will evaluate Trump's second term. The vote will also test support for Trump's trade policies in rural areas. The state's farming communities helped Trump win here in the general election, but they are now particularly upset about tariffs. For his part, Mr. Musk has a stake in a campaign in which he threw money behind Schimel and the state Supreme Court may soon hear a case related to a state law that prohibits automakers from selling cars directly to consumers, which Tesla has challenged.
