Former Republican U.S. Sen. Gordon Humphrey and former New Hampshire First Lady Dorothy Peterson are among 100 independent Granite State voters announcing their support for former Vice President Joe Biden on Monday.

The Biden campaign said 93 of the 100 “New Hampshire Independents for Biden” are making their support for the former vice president known for the first time. The other seven have been previously announced and are reaffirming their support as members of the grassroots coalition.

The campaign said it intends to make a broad, concerted effort to speak to independent voters over the next six weeks leading to the first-in-the-nation primary on Feb. 11.

Independents, formally known as undeclared voters, make up the largest voting bloc in the state. As of Oct. 30, they comprised 42 percent of the registered voters in the state, while Republicans were 29.5 percent and Democrats were 28 percent of New Hampshire voters.

Independents can take either a Democratic or a Republican ballot in primary elections and then are able to return to undeclared status if they wish.

The Biden campaign said the independent voters on its supporters’ list “believe Joe Biden is the best candidate to defeat President Trump and restore the soul of our nation.”
