*politicians* of both parties engage in obfuscation and misdirection, but liberal politicians favor semantic pedantry.
but liberals, who are NOT politicians, choose these tactics far more often than their opponents, because it is the liberal who sees himself as a nuanced, sophisticated intellectual, and it is the liberal who concocts complicated rationalizations for flimsy ethical positions, engages in semantic games to obfuscate and change the subject, proposes endless false analogies, and cites theoretical hypotheticals and utopian platitudes ad nauseum. Yes, that may be true but we are not nearly as good at putting forth unsupported assertions with the same glib aplomb that you conservatives do.
