California's 40th congressional district

Early voting opens Oct. 15 and runs through Oct. 31 in North Carolina, a key battleground in the 2025 midterms. The marquee race is the open U.S. Senate seat left by retiring Republican Thom Tillis, pitting Democrat and former Gov. Roy Cooper against Republican Michael Whatley, the Trump-backed former RNC chair, with Green and Libertarian candidates also on the ballot. Democrats are targeting the seat as part of a broader push to flip the four seats needed for Senate control.

The ballot also includes competitive U.S. House races, including Charlotte-area districts held by Reps. Alma Adams, Tim Moore and Mark Harris, plus down-ballot contests for the N.C. Supreme Court, Court of Appeals, state legislature, and Mecklenburg County offices. Voters will also weigh in on constitutional amendments covering voter ID, income tax caps and property tax limits, along with Charlotte bond measures for transportation, housing and neighborhood improvements. Election Day is Nov. 3, with North Carolina's results seen as a bellwether for national party control in Washington.

California voters head to the polls in November to decide statewide and local races alongside 14 ballot propositions, including a closely watched "billionaires tax" measure and a recall-process reform. San Diego County's voter guide outlines a packed slate of contests, with voter pamphlets mailed in late September and ballots beginning to arrive October 5.

Key federal races include five competitive U.S. House districts (48–52), pitting incumbents and challengers from both parties after redistricting reshaped several seats. State Senate and Assembly races feature multiple incumbents defending seats, while the California State Board of Equalization's District 4 race pits a local water official against a sitting state senator.

Locally, San Diego County voters will also choose county supervisors, school board members, and city officials across numerous municipalities including San Diego, Chula Vista, Carlsbad, Escondido, Oceanside, and others, alongside mayoral races and special district seats covering healthcare, water, and community college boards. The wide-ranging ballot reflects a highly competitive election cycle across Southern California.
