Incensed, McCain ran ads accusing Bush of lying and comparing the governor to Bill Clinton, which Bush said was "about as low a blow as you can give in a Republican primary". An anonymous smear campaign began against McCain, delivered by push polls, faxes, e-mails, flyers, and audience plants. The smears claimed that McCain had fathered a black child out of wedlock (the McCains' dark-skinned daughter was adopted from Bangladesh), that his wife Cindy was a drug addict, that he was a homosexual, and that he was a "Manchurian Candidate" who was either a traitor or mentally unstable from his North Vietnam POW days. The Bush campaign strongly denied any involvement with the attacks.
