US election live: Polls open in most states in tight Harris vs Trump race

Let’s bring you up to speed:

• Polls are open in more than three dozen states across the eastern and central United States, where voters are casting their ballots for the next president.
•  Alongside the presidential race, hundreds of congressional seats are at stake, which will shape the party balance in the House and Senate, and thousands of local offices are also on the line. In 10 states, referendums on abortion rights are on the ballot.
• Democratic candidate Kamala Harris and Republican candidate Donald Trump are polling neck and neck in the seven swing states likely to decide the presidential race, which experts say could go either way.
• The economy, democracy, national security, immigration, education and healthcare are among voters’ top concerns as they head to the polls.
