RICHMOND, Va. (AP) -- Virginia voters won't be allowed to wear clothing featuring John McCain or Barack Obama when they head to the polls on Nov. 4.

The State Board of Elections on Tuesday voted to ban clothing and hats as well as buttons and other paraphernalia that directly advocate the election or defeat of a specific candidate or issue.

The American Civil Liberties Union argued that the ban violates the First Amendment's right to free speech. The board, however, said it has to weigh that against the right to vote free of undue influence or the tension that candidate advocacy might create.

Efforts to enforce a similar ban are headed to court in Pennsylvania. At least four states -- Maine, Montana, Vermont and Kansas -- prohibit wearing campaign buttons, stickers and badges inside polling places.
