A new Washington Post poll found that 74 percent of Americans support having voters show ID at the polls, and a full 81 percent think voter fraud is a problem.

They have reason to be concerned. This month, four staffers for former Michigan congressman Thad McCotter were indicted for forging signatures on petitions to place him on the ballot. McCotter resigned from Congress after evidence surfaced that his district office had been run like a political version of Animal House.

Now, the Detroit Free Press reports that McCotter, Inc. had apparently been forging petitions for years, and he didn’t actually qualify for the ballot in at least the 2008, 2010, and 2012 elections. The Free Press reports that data archivists found that “in 2008, at least 67 of the 177 petition pages submitted were either copies or had been doctored by cutting and pasting dates from other documents onto the petitions.” In 2010, at least 73 of the 167 pages turned in were duplicates, which would have invalidated more than 1,000 of the signatures. In 2012, the scheme had evolved to the point that of the 1,800 signatures submitted by the McCotter campaign, only 244 were valid. But that year, the fraudsters saw their luck run out when a part-time worker for the Michigan secretary of state spotted the fraud. New procedures will make it more difficult to commit such fraud in the future.
