Much adieu about nothing but it is kind of funny. Biden isn't the first vice president to get criticized for language such as this. Remember the furor over Dick Cheney telling Sen. Pat Leahy to "go f..k yourself"? And, of course, we have the Nixon watergate tapes to reference for colorful use of foul language.
Note to republicans and conservatives: this is so petty an issue and using it only illustrates how impotent you've become. If you hadn't dropped the ball over the last ten years and sold out to corporate handlers this health care bill would probably still be dead on arrival like all the previous attempts.
