Brad Blog has this story, which says Virginia law enforcement officials are looking into the possibility that a petitioner for Newt Gingrich may have forged names on petitions. It seems somewhat likely that no such investigation would now be occurring if Gingrich himself had not told an Iowa voter in public that “one guy” who worked on his petition submitted 1,500 fraudulent signatures. Thanks to IndependentPoliticalReport for the link.
The Brad Blog story also talks about whether Mitt Romney was improperly registered to vote in Massachusetts in January 2010, when he voted in the special U.S. Senate election.
