It's Election Day in the US.
This so-called "off year" election doesn't feature presidential or congressional races, but there are still several critical votes to watch tonight.
New York City will choose its next mayor, in a battle that has pitted a younger, progressive Democrat against a member of the party's old guard. The states of Virginia and New Jersey will elect new governors, and the outcome of these contests could be bellwethers for next year's congressional midterm elections.
Californians also will decide whether to redraw their US House district maps in a rare mid-decade redistricting, as Democrats try to counter Republicans' efforts to give their party an advantage in next year's midterm elections.
Here's what you need to know.
