US election 2020: What you need to look out for

The first polls will close in Indiana and Kentucky at 6 pm Eastern Time Tuesday, while the last polls will shut down in Alaska at 1 am ET Wednesday.

Since many Americans are voting by mail-in ballots, it's likely that early partial results would be misleading. States counting in-person votes first will probably favor Trump, while states counting pre-Election Day votes might favor Biden.

The states of Indiana and Kentucky are not crucial to focus on since President Trump is expected to win against his Democratic rival here. Kentucky Senator Mitch McConnell is also likely to win easily.

However, early trends will not reveal much about the results, since polls will remain open in both states for another hour in the western regions that follow Central time.

Florida and Georgia are expected to count the ballots faster compared to other swing states.

Biden's victory in either state would be significant. However, it must be noted that Florida reports pre-Election Day votes first and polls in the state's conservative Panhandle region will be open for another hour; both these factors imply that early trends could disproportionately favor the Democrats.

Notably, North Carolina and Ohio are swing states that are likely to report a majority of the votes quickly. However, both states will continue to accept mail-in ballots for over a week. The winner may not be apparent until mid-November in a close race.

North Carolina also has a competitive Senate race this year between Senator Thom Tillis and Democrat Cal Cunningham.

The last polls in Florida will also close at this time, along with most or all polls in key swing states Michigan, Pennsylvania, and Texas.

Texas will likely report most votes by Tuesday night while Michigan and Pennsylvania may take several days. Early trends may disproportionately favor Republicans.

Alabama, Maine, Michigan, and Texas also have significant Senate races.

Arkansas wouldn't tell us much as it's safe Republican territory for Trump and Senator Tom Cotton. There is, however, a competitive 2nd Congressional District race.

Polls close in Arizona, Colorado, Minnesota, and Wisconsin at 9 pm ET. Democrats are hoping to flip Senate seats in Arizona and Colorado. These states report votes fairly quickly. Final results in Wisconsin may be out by Wednesday morning.

Although Iowa is more Republican-leaning in the Presidential race and is less likely to decide the election compared to other swing states, if Biden wins here, he would probably have passed 270 electoral votes elsewhere. The same is true for Trump in Nevada.

Iowa has one of the most competitive Senate races this year, between Senator Joni Ernst and Democratic challenger Theresa Greenfield.

None of the states where polls close at 11 pm ET have competitive Presidential or Senate races.

California has several noteworthy House races, however, the complete results may not arrive for weeks. Notably, several California residents voted by mail even before the pandemic.

Hawaii's results may be reported quickly, however, there wouldn't be much to see in the Hawaii or Alaska polls.
