TALLAHASSEE, Fla. (AP) - The American Civil Liberties Union of Florida is suing to stop enforcement of a new elections law that critics say was written to discourage voters likely to support Democrats.

ACLU Florida argues in the suit filed Friday that the changes in election law must first be approved by the federal Justice Department to ensure that they aren't discriminatory.

The law created tighter restriction on groups that conduct voter registration drives, requires voters who change their address at the polls to cast a provisional ballot and reduces the number of early voting days.

Critics say minorities are often the target of voter registration drives and that the provision that doesn't allow voters to cast a regular ballot if they've changed addresses will disproportionately affect lower income residents and college students.
