The first general election since Donald Trump became president is underway, with several high-profile races on the ballot.
More than half of the states will hold contests on Tuesday, including elections for governor in Virginia and New Jersey, mayor of New York City, and a proposition in California to redraw congressional district boundaries.
The results of these contests will be seen as either a repudiation or approval of Trump's second-term agenda.
