A record 200 million Americans are registered to vote in Tuesday’s election, and most of those who haven’t already mailed in ballots or engaged in early voting will have until 6-9 p.m., local time, to cast their ballots.

Oregon and Washington conduct their elections entirely by mail. Colorado mails ballots to every voter but voters have a choice of casting ballots by mail or in person.

The number of registered voters marks shifting demographics on the political landscape. Turnout, on the other hand, is a separate issue. Only 53 percent of eligible voters participated in the 2012 general election, the Pew Research Center reported.

Weather is not expected to be a major factor Election Day, with dry conditions and above-average temperatures forecast for much of the country, weather.com reported. Rain is possible in the battleground states of Michigan and Ohio as well as in Illinois, Indiana and Missouri. Rain also is possible in Texas, Louisiana, Mississippi, Arkansas and western Tennessee.

Though approximately 40 percent of expected votes already have been cast via absentee or mail-in ballot, or through early voting, remaining voters will have all day to go to the polls. And if anyone is in line at closing time, local law generally allows the voting to continue until all ballots are cast.
