How far left could Obama's Supreme Court nominee push the Supreme Court? Pretty far (Kerry Eleveld) from Daily Kos
"Here's some good news for progressives: Scoring from four political scientists suggests that President Obama's Supreme Court nominee, D.C. Circuit Court Judge Merrick Garland, would land to the left of six sitting justices, including Elena Kagan and Stephen Breyer, who are both considered to be part of the court's liberal cohort. Only the notorious Ruth Bader Ginsberg and Sonia Sotomayor score to the left of Garland according to their history of rulings."
