US voters go to the polls today with outcome unclear

Significance The outcome remains unclear in the presidential race and in the contest to control the House of Representatives, but Republicans appear on course to win by a very slim margin in the Senate. Impacts Exit polling should give an indication very late tonight if there is any sign of an unanticipated swing to either presidential candidate. President Joe Biden remains in office until January 20, making him responsible for the federal response to any post-election disturbance. Recent expressions of confidence by the Trump camp seemed designed to set the scene for challenging a Harris victory. The electoral calendar allows for several weeks of court challenges to the ballot tallies that will be reported over the next few days.
