The first general election since Donald Trump became president is being held, with several state and local elections taking place.
These elections include high-profile races for Virginia and New Jersey governor, New York City mayor, and a California proposition to redraw congressional district boundaries.
The results of those contests will be heralded by the victors as either a major repudiation or resounding stamp of approval of his second-term agenda.
More than half of the states will hold contests on Tuesday, making this a significant election day.
