What to expect as voters test Trump’s sway and party power from New York to California

Off-year elections, including Zohran Mamdani's high-profile New York race, could reshape the political map

Voters in several states are heading to the polls on Tuesday for elections that will provide a crucial window into nationwide support for Donald Trump's Republican allies, and potentially signal new momentum for the beleaguered Democratic party.

The off-year elections could see Democratic insurgent Zohran Mamdanibecome the next mayor of New York City, while voters in deep-blue California could tear up their congressional maps in favor of a Democratic gerrymander meant to counter gains the GOP is expected to make elsewhere. And Virginia and New Jersey will hold high-stakes gubernatorial and legislative elections that may serve as a proxy for voters' views on the president.
