The next presidential election isn’t until 2020, but speculation is already off to the races.

High-powered Hub attorney William F. Weld, the former governor of Massachusetts and the Libertarian Party’s 2016 nominee for vice president, has rejoined the Republican Party that made him a rising political star.

Gale McHugo, Canton’s assistant town clerk, said Weld, 73, came in Jan. 17 and changed his party affiliation from Libertarian to Republican with a form process that took “less than a minute. It was very matter of fact and the same thing we would do for any voter.

“He did not say a word about running for president,” McHugo responded when the Herald pressed. “We don’t ask.”

Weld, who owns a century-old $1.26 million manse in town with novelist wife Leslie Marshall, 65, “was very personable,” McHugo said.

Weld did not immediately respond to a request for comment.

The Harvard Law graduate and member of the prestigious Mintz law firm is a former assistant U.S Attorney General who oversaw the criminal division of the Justice Department. He has also served as U.S. Attorney for Massachusetts.

Weld served as 68th governor of the Bay State from 1991 to 1997.

In 2016, after abandoning the GOP, he made an unsuccessful run for the White House alongside Libertarian presidential nominee Gary Johnson, a former governor of New Mexico.
