After years of defending Clinton, liberals love the piquant irony of calling Bush a liar. For 50 years liberals have called Republicans idiots, fascists, anti-Semites, racists, crooks, shredders of the Constitution and masterminds of Salvadoran death squads. Only recently have they added the epithet "liar." Even noted ethicist Al Franken has switched from calling conservatives "fat" to calling them "liars."
This is virgin territory for Democrats -- they never before viewed lying as a negative. Their last president was called "an unusually good liar" by a sitting Democratic senator. Their last vice president couldn't say "pass the salt" without claiming to have invented salt. Having only just discovered the intriguing new concept of being offended by lies, the Democrats are having a jolly old time calling Bush a liar. But they can't quite grasp the concept of a lie as connoting something that is -- at a minimum -- untrue.
