MIAMI (AP) — With a week to go until Election Day, the nasty campaign tactics are coming out.

People in Florida, Virginia and Indiana have gotten calls falsely telling them they can vote early by phone and don’t need to go to a polling place. Indiana’s secretary of state launched an investigation. Virginia officials issued a warning to voters and asked them to report any such calls they receive.

And there’s a mysterious DVD popping up in mailboxes that purports to be a “documentary” raising questions about the true identity of President Barack Obama’s father.

It’s one more sign of just how close this presidential election is.
