There’s lots of uninformed buzz on Twitter today about a report purporting to show 141 percent voter turnout in St. Lucie County, Florida:
Twitter user @NathanWurtzel points out that the figure is based on “cards cast,” which is not the same as votes cast.
It appears that “cards cast” refers to the number of ballots times the number of pages on each ballot. So if the ballot is two pages long, “cards cast” should be twice the number of ballots cast.
Does voter fraud exist? Yes.
Is it prevalent enough to explain Barack Obama’s margin of victory (about three million votes nationwide, about 74,000 votes in Florida)? No.
