Shorter Stephen Bainbridge: Democrats are crazy, too!

Reacting to David Frum's absolutely devastating beatdown on the GOP, Bainbridge writes,

If the leadership of the left consisted of people of moderate views, sound judgment, even temper, and good will, unilateral disarmament of the sort David seems to contemplate might make sense.

Leadership of the left: Obama, Biden, Clinton, Reid, Schumer, Kerry.
Leadership of the right: McConnell, DeMint, Boehner, Cantor, El Rushbo

Which side is more "moderate" and "even tempered"?
