There should be only one, but we may never know. Apparently he's also registered (falsely) in Nevada.
Bob Walsh, spokesman for the Nevada secretary of state's office, told FOXNews.com the raid was prompted by ongoing complaints about "erroneous" registration information being submitted by the Association of Community Organizations for Reform Now, also called ACORN.
The group was submitting the information through a voter sign-up drive known as Project Vote.
"Some of them used nonexistent names, some of them used false addresses and some of them were duplicates of previously filed applications," Walsh said, describing the complaints, which largely came from the registrar in Clark County, Nev.
Secretary of State Ross Miller said the fraudulent registrations included forms for the starting lineup of the Dallas Cowboys football team.
"Tony Romo is not registered to vote in the state of Nevada, and anybody trying to pose as Terrell Owens won't be able to cast a ballot on Nov. 4," Miller said.
At least in Nevada they're taking it seriously. In Nevada, the cross-checking is preventing the fake registrations from making the rolls. Unfortunately in Wisconsin the state government agency in charge of elections is not interested in doing a proper check, and is actually preventing local clerks from doing a check themselves.
