O'Reilly has acknowledged that from 1994 until December 2000, he was registered to vote as a Republican. He changed his voter registration from Republican to independent when the Washington Post was about to expose his party affiliation.
Now a registered independent, O'Reilly has said his previous affiliation was the result of a clerical mistake, and that no box for 'independent' was available on the registration form.
