Stevens has announced he’s retiring. He was appointed by Ford, and is 90 years old this April 20th. This is actually a pretty significant blow to the folks who voted against us in Heller, and likely in McDonald too. Stevens was widely regarded as the intellectual leader of the left-leaning side of the Court. It’s widely expected that Obama will get a third pick for the Court when Justice Ginsberg retires. The 2010 elections are only increasing in importance.
Obama will, of course, replace Stevens with a similar lefty, but it’ll be hard to replace his leadership on the Court.
