When Sen. Ted Cruz rolled out an epic 21-hour anti-Obamacare "filibuster," his efforts were ridiculed by journalists across the Twitterverse as a useless exercise in would-be obstructionism. No surprise there. Senate Majority Leader Harry Reid took to the Senate floor, as well, and declared Cruz's efforts a waste of time, unpacking his standard lament about the lack of compromise in Washington. If only today's "anarchists" (Reid's description) would play ball, we'd get stuff done. But as David Harsanyi observes, believe it or not, compromise isn't a holy sacrament. In fact, politics is the art of compromising as little as possible.
