WASHINGTON — Voters across the United States head to the polls today for midterm elections expected to shape the remainder of Donald Trump’s second presidential term. Democrats are looking to capitalize on sliding presidential approval ratings to capture control of Congress and establish checks on the administration's executive authority.

The high-stakes balloting unfolds against a backdrop of legal and administrative battles over voting procedures. In California, the Department of Justice recently filed voter fraud charges against six additional individuals, marking an escalation in federal election integrity efforts. Simultaneously, the US Supreme Court dealt the administration a setback by blocking attempts to force state election officials to segregate ballots belonging to voters flagged by the Justice Department as non-citizens.

Guardian correspondents reporting from the field highlight competitive races nationwide. In New Hampshire, Republicans concerned about Trump's potential drag on the ticket are working to flip a Senate seat, while campaigns in Texas, California, and Michigan showcase shifting political dynamics and key local contests.
