From Wikipedia: Despite popular belief that "Dear Mr. President" would be released as a single, during a promotional visit to Australia, Pink appeared on the TV show Rove Live and said that the track would never be released commercially, despite unexpected
radio airplay in some markets. Pink also mentioned during a radio interview in Seattle on KISS 106.1 that she would not release "Dear Mr. President" as a single because she didn't want people to think it was a publicity stunt.
