Head in the sand is saying that people won't forget some other guy saying "God damn America" but will forget Clinton telling blatantly false fish stories about being in a combat zone.

Head in the sand is basing your candidacy on your ability to fight through smears like Monica, Whitewater, Travel Office scandal, Vince Foster, lesbianism, Kazikhstan, and the pardons of 140 friends on the last day of Bill's presidency, and then suggest that your opponent is finished by his relationship with one angry black man who said a few angry things at a government that had oppressed his people for hundreds of years.
