Election day voters go to the polls in New York
Voters in the New York City started casting their ballots on Tuesday in the first national election of Joe Biden's US presidency. With polls open, Democrats were braced for disappointing results, anxious that their grip on the US House may be slipping and that their hold on the US Senate — once seen as more secure — has loosened. Thirty-four Senate seats are up for grabs with cliffhangers in Pennsylvania, Georgia, Wisconsin and Arizona possibly deciding which party controls a chamber currently split 50-50, with Vice President Kamala Harris as the tie-breaking vote. Democrats are hoping for upsets in Ohio and North Carolina's Senate contests, while the GOP believes it can oust a Democratic incumbent in Nevada and possibly in New Hampshire. Thirty-six states are electing governors, with Democrats particularly focused on holding control of Michigan, Wisconsin and Pennsylvania. Every seat in the US House is also up for election.
