It saddens me to admit it, but the evidence is too overwhelming to dismiss: Democrats are significantly more cunning than Republicans.

I say “Democrats,” but that is an imprecise, even a misleading, designation. Party affiliation is not now, if it ever was, a really accurate predictor of ideological coloration.

What I mean are those people, most of whom happen to belong to the Democratic Party, who have been bitten by the bug of extremism, who are fired by revolutionary fervor, who regard every opponent, every contrary opinion, as a “by-any-means-necessary” fire alarm.
