The 2020 election is already in full swing as tens of millions of voters have cast their vote through the mail or at early voting sites.

A lot is riding in this year's races and ballot measures, all under the shadow of the coronavirus, which has changed the way the public is taking part in this year's vote and how candidates are approaching their races.

An unprecedented number of mail-in votes is expected this year, as voters try to stay safe from the novel coronavirus, but droves of Americans are donning masks and heading to the polls in person ahead of Election Day on Nov. 3 as well. The novel environment has led to concerns and a host of legal challenges, including the deadline for ballots to be accepted in some states, and more litigation could follow Election Day.

And beyond the race for president between Donald Trump and Joe Biden, the balance of power in Congress is at stake as well as a slew of consequential statewide and local races.

ABC News is not only bringing you the latest reporting from the trail, but also publishing a series of pieces to help navigate the complex issues surrounding this election.
