Roberts completes the 4 Horsemen of the Apocalypse
Supreme Craptacular:

those who know Roberts say he, unlike Souter, is a reliable conservative who can be counted on to undermine if not immediately overturn liberal landmarks like abortion rights and affirmative action. Indicators of his true stripes cited by friends include: clerking for Rehnquist, membership in the Federalist Society, laboring in the Ronald Reagan White House counsel's office and at the Justice Department into the Bush years, working with Kenneth Starr among others, and even his lunchtime conversations at Hogan & Hartson. "He is as conservative as you can get," one friend puts it. In short, Roberts may combine the stealth appeal of Souter with the unwavering ideology of Scalia and Thomas.

The Roberts, Scalia, Thomas, and Bush-appointed Rehnquist-successor will be a scary conservative quartet intact for maybe the next 15 + years. After Rehnquist, the next to go are likely to be Stevens and Ginsburg. If we don't start winning elections and soon, we're not much going to recognize our privacy or first amendment rights by the time 2020 comes around.
