Vermont: Here’s how to vote, where to vote and what’s on the ballot.

Vermonters head to the polls Tuesday to choose nominees for the state’s lone House seat as well as the Senate seat being vacated by Senator Patrick Leahy, a Democrat who is retiring.

Not registered to vote? No problem. Thanks to Vermont’s same-day voter registration laws, adults who live in the state can still cast ballots in Tuesday’s primaries.

Here’s what to know:

How to vote

If you need to take advantage of same-day registration, do it in person — either at your polling location, or during normal business hours at town clerks’ offices. Online registrations may not be processed in time for voting on Election Day.

If you are voting by mail, make sure your ballot is received by election officials before the end of Election Day. If you have not already mailed your ballot in, drop it off at your town clerk’s office before it closes or at a polling location until 7 p.m. Eastern time.

According to a rule introduced in 2020, the secretary of state’s office mails ballots to every registered voter ahead of the general election in November. But primary elections are not subject to that rule, and the deadline has passed to receive an absentee ballot for Tuesday’s contests.

Polling locations are equipped with tablets to accommodate voters with disabilities. Here is more information about accessible voting in Vermont.

Where to vote

Find your polling place on the secretary of state’s website here.

Most towns in the state offer voters the option of depositing absentee or mail ballots in designated drop boxes. You can find information about voting in your town by visiting your town’s website. Here’s how to look that up.

What is on the ballot

Mr. Leahy will retire in January, at the end of his current term. The state’s current at-large representative, Peter Welch, leads the Democratic contest to replace him.

Becca Balint, the president pro tempore of the State Senate, will face off against Lt. Gov. Molly Gray in the Democratic primary for the seat being vacated by Mr. Welch. Each woman is running with the backing of one of Vermont’s senators: Ms. Balint is endorsed by Senator Bernie Sanders, and Ms. Gray is endorsed by Mr. Leahy.

Phil Scott, the blue state’s uber-popular Republican governor, will face two challengers in his party’s primary in his quest to win a fourth term in Montpelier.
