Tonight's elections are a Trump, Musk referendum in pivotal tests for both Republicans, Democrats

Tonight's elections are seen as a referendum on the policies of former President Donald Trump and billionaire entrepreneur Elon Musk, who made a surprise bid to run for governor in Nevada. Voters will also be deciding on various congressional and state-level seats, with some races pitting Democrats against Republicans in closely contested battlegrounds. The outcome is expected to shape the balance of power in Washington, D.C. and influence the direction of the country's policy agenda.
