Seeing as I've copied Jane's title, I'll add another Firedoglake contributor for his synopsis on this:
Finally, after years of obfuscation and euphemism by our Versailles Traditional Media, a great wall has been broken down. During a debate at MSNBC about whether the current Administration should uphold the Rule of Law and conduct investigations of Dick Cheney's secret-from-Congress intel programs, Marcy Wheeler (Emptywheel) provided the taboo word at the center of the Ken Starr investigation, by saying BLOWJOB on television.
The only thing I'll add is that it would be a damn shame if the powers that be used this as an excuse to keep Marcy off their GE-controlled network.
