Three key races, California's map and the Trump factor - what to watch in US elections

The US elections feature key races in New York City, California, Virginia, and New Jersey. New York City's mayoral race is a highlight, with Zohran Mamdani challenging for mayor. California's Proposition 50 seeks voter approval for mid-decade redistricting. New Jersey and Virginia governor races will show the country's political climate. The outcome could serve as a bellwether for next year's Congressional midterms, and elections are taking place without the presence of Trump.
