CONCORD, N.H. – A second lawsuit is challenging a pending voter residency law in New Hampshire.

The New Hampshire Democratic Party filed the federal suit Wednesday against Secretary of State William Gardner and Attorney General Gordon MacDonald. The American Civil Liberties Union sued earlier.

The law takes effect July 1. Current law allows people to vote who consider the state their “domicile,” that is, counting the state as their place of residence “more than any other place.” The new law makes residency a condition of voting in the state, requiring people who register to vote to get a New Hampshire driver’s license and registration.

The Democratic Party says the new law is unconstitutional.

Gardner has said he sees the issue as “everyone who votes ought to vote under the same standards.”
