Times have changed. I'd swear that the Republicans are having an on-line version of the 1968 Democratic convention in Chicago. No one's getting his skull thudded by a police baton, but in a virtual sense, it's turning out just a bloody.

Actually, the parallels are interesting:  the President is unpopular and is leading an unpopular war. The nominee is tied to the war and can't break free. The opponent is promising some vague way out. And the factions in the President's party are far more pissed at each other than the factions in the opposition.
