So far, there haven't been widespread reports of problems at polling locations in the wake of Donald Trump's exhortations about a rigged election. Maybe because his most fervent supporters bought it, think it's all rigged, so they're not bothering. Possibly they got the message handed down from Roger Stone at the last minute to obey the law. But it's worth knowing the laws regarding voting—so that when you go to the polls, you know what to look out for.
1) Threats or intimidation
It's illegal under federal law for people to conspire to "injure, oppress, threaten, or intimidate" you to get you to vote a particular way for president, vice president, or, notably for midterm elections, a member of Congress.
Know what information is required to vote in your state and if a poll worker tries to intimidate you by asking for more documentation than is legally required to vote, demand to see a supervisor. Additionally, look out for "poll watchers" trying to approach voters or hand off materials too close to the polling location.
2) Getting shut out of the polling place after waiting in line
There's no specific law addressing how long is too long when it comes to waiting in line to vote, but Ho said waits as short as an hour and as long as eight hours have been found by courts to violate voters' rights.
Regardless of how long the line is, the important thing is that you must be allowed to vote as long as you're in it before the polls close. So if you're in the back of a long line at 7:25 and there are still several people ahead of you when the polls close at 7:30 (if that's the closing time at your polling place), you can't be turned away.
If you're in line before the poll closing time, you have the right to vote. Stay in line.

3) Overzealous ID checks
Voter ID laws require voters to show some form of identification, such as a driver's license or passport, at the polls before they cast a vote. States without voter ID laws generally have "non-documentary" identification requirements, under which voters can verify their identity in other ways, such as by signing an affidavit or poll book or by providing personal information like their address or birthdate.
Know what you need to bring with you to the polls.
4) Getting turned away without casting a provisional ballot
State voter ID laws differ when it comes to what happens to voters who can't produce the required identification. States with strict voter ID laws require voters who don't have the proper ID to vote using a provisional ballot and then take additional steps after Election Day (for example, returning to the election office with an ID) to ensure that their votes are counted.

5) No polling place can accommodate your disability Polling places are required by federal law to be accessible to people with disabilities. If your own polling place isn't suitable — unable to accommodate wheelchairs, for example — the Voting Accessibility for the Elderly and Handicapped Act of 1984 requires election officials to make sure you have an alternative way to cast a ballot. […]
6) Bribery The only thing you should ever allow anyone to give you in exchange for casting your ballot is that little "I Voted" sticker that lets you show off to your colleagues that you've done your civic duty.
While laws vary by state, typical statutes prohibit anyone from giving you (or offering, lending, or promising to give or lend you) anything to get you to vote, refrain from voting, or vote a certain way.
That last one is kind of a bummer—no free ice cream cone with your "I voted!" sticker? But it might very well be the law in your state.
