Polls closed at 8 p.m after a day of steady voting in every Island town in the much-watched presidential primary.

Vineyarders joined residents from 14 states, including Massachusetts, to cast votes on the day of the biggest delegate haul in the presidential primary race — familiarly known as Super Tuesday.

Early numbers suggested that turnout throughout the Island was strong.

By 7:30 a.m., voters were already lined up outside of the Oak Bluffs library to cast ballots. Although the line had died down by one o’clock, town clerk Laura Johnston said that townspeople had cast 625 ballots — not including the town’s 350 early and absentee votes.

Similar numbers were tallied in Tisbury, where approximately 25 per cent of eligible voters in town had already cast ballots by noon. Town clerk Hilary Conklin said the flow of voters had been constant.

“We want to break the last primary’s record,” Ms. Conklin said. “One minute it will look like it’s starting to slow down, then boom, lots of people come in at once.”

Edgartown had over 1,000 ballots cast by 2:30 p.m., with town clerk Karen Medeiros also saying that turnout had been steady throughout the day. Approximately seven per cent of registered Islanders voted early, according to initial results.

In both West Tisbury and Edgartown, total registered voter numbers are up relative to the 2016 presidential primaries and the 2018 midterm primaries. Edgartown has approximately 200 more registered voters than 2016, while West Tisbury has about 80 more.

Massachusetts represents 91 of the 1,357 Democratic delegates up for grabs throughout the country. Recent polls have shown a tight race in the state for the Democratic delegates between Sen. Elizabeth Warren and Vermont Sen. Bernie Sanders. Delegates will be awarded proportionally to candidates who achieve greater than 15 per cent of the vote share.

The only remaining candidate to hold a public event on the Vineyard during the 2020 presidential election cycle, South Bend Mayor Pete Buttigieg dropped out from the race on Sunday. Minnesota Senator Amy Klobuchar has also dropped out.

In Tisbury, hand sanitizer pumps and hygienic wipes were available for voters at the polling station. Other town clerks also said precautionary measures were taken to keep ballot booths clean and sanitary.

There was no shortage of animals at the polling stations on Tuesday, either. Dogs were commonplace in all the down-Island towns, and one voter in Oak Bluffs even brought an emotional support Macaw, the tropical white bird accompanying its owner to the ballot box. Despite its squawks, the bird did not disrupt the voting flow, Ms. Johnston said. In fact, the Macaw was seen as a welcome non-partisan voice.

“He behaved and was a good bird,” Ms. Johnston said. “He didn’t have anything political to say.”
