A new report by the Pew Center on the States finds that more than 1.8 million dead people are currently registered to vote.
And 24 million registrations are either invalid or inaccurate.
There's little evidence that this has led to widespread voter fraud [ ??? ], but it has raised concerns that the system is vulnerable....
For some perspective, consider the popular vote in 2008: Obama received 69.4 million votes to McCain's 59.9 million -- a difference of "only" 9.5 million.
