Mitt Romney can count Martha’s Vineyard among his Super Tuesday victories.

The Island, like the rest of Massachusetts, overwhelmingly voted for Mr. Romney in the Republican primary on Tuesday, with the former governor receiving 64 per cent of the Republican vote. Mr. Romney won 72 per cent of the vote statewide in Massachusetts, which was one of 10 states to hold primary elections on Tuesday.

Former Pennsylvania Sen. Rick Santorum placed second on-Island with primary voters, with about 16 per cent of the vote. Rep. Ron Paul placed third, with 13 per cent, and former House speaker Newt Gingrich came in last among the four candidates, with about six per cent.

While the Republican race was the one to watch, Democrats also voted in the primary, in which President Barack Obama ran unopposed. Mr. Obama received 93 per cent of Democratic votes. Some voters opted for “no preference” or left their ballots blank. Ron Paul received one vote on a Democratic ballot in West Tisbury.

With 644 total votes on the Island, Mr. Obama topped Mr. Romney, who received 610 votes.

“A lot of people thought it was only a Republican election,” said Edgartown town clerk Wanda M. Williams.

Ms. Williams said that election day was “slow and quiet . . . it was quite uneventful.”

“Lack of voter turnout makes for a very long day,” said Tisbury town clerk Marion A. Mudge.

Islandwide, 12.8 per cent of registered voters — 1,655 out of 12,938 — cast ballots.

In Oak Bluffs, Mr. Romney won the primary by the highest margin, with 71 per cent of the vote, 172 out of the 243 ballots cast. Mr. Santorum was second in Oak Bluffs with 41 votes. Mr. Paul, with 18 votes, and Mr. Gingrich, with 11 votes, finished third and fourth, respectively.

Mr. Romney won 184, or 64 per cent, of 285 votes cast on the Republican ballot in Edgartown. Ron Paul came in a distant second with 41 votes. Rick Santorum received 32 votes and Newt Gingrich 15 votes.

In Vineyard Haven, Mr. Romney captured 63 per cent of the Republican vote, or 138 out of 219 ballots. Mr. Santorum came in second with 40 votes, while Mr. Paul got 30 votes and Mr. Gingrich nine.

Fifty-six per cent of the vote went to Mr. Romney in West Tisbury, with 85 out of 153 Republican ballots cast in his favor. Mr. Santorum received 27 votes; Mr. Paul, 22 votes; and Mr. Gingrich, 19 votes.

Sixty-three per cent of voters went for Mr. Romney in Chilmark — 29 of 46 Republican ballots. Ten Chilmark voters opted for Mr. Paul. Mr. Santorum received seven votes.

But in Aquinnah it was Mr. Paul who claimed victory. The Texas congressman received four votes, half of the eight Republican ballots cast. Mr. Romney got two votes; Mr. Santorum and Mr. Gingrich received one apiece.

President Obama received 155 votes in West Tisbury, 141 votes in Oak Bluffs, 138 votes in Vineyard Haven, 106 votes in Edgartown, 74 votes in Chilmark and 30 votes in Aquinnah.

Chilmark had the highest turnout of Island towns — 14.7 per cent, or 129, of the 877 registered voters went to the polls. About 13 per cent of West Tisbury’s 2,358 registered voters and 12.8 per cent of Edgartown’s 3,160 registered voters cast ballots. In Vineyard Haven, 12.7 percent of 2,896 registered voters turned out, as did 12 per cent of 3,256 registered voters in Oak Bluffs. The turnout was about 10 percent in Aquinnah, where 39 of 391 registered voters cast ballots.

Several candidates who have since dropped out of the race collected votes on-Island. Former Republican contender John Huntsman, who withdrew his candidacy in January, received seven votes. Former Republican candidates Rick Perry and Michele Bachmann each received votes in Edgartown.

Eight people voted on Green Party ballots.
