If California required voters to provide identity documents at the polls, the official popular vote count might be very different. California is one of eighteen states where documentation is not required in order to vote. Such laxness provides ample opportunity for voting irregularities. In order to ensure that Presidential elections are viewed as free and fair, the United States needs to implement a uniform system of voter identification - preferably photo i.d. - in all fifty states (fifty-seven according to Obama) and the District of Columbia.
