Brad Plumer's not surprised,
The idea that McCain would let Sam Brownback do the honors of picking John Paul Stevens's replacement is terrifying, but not unexpected. People like Jacob Weisberg have occasionally suggested that, despite McCain's zero rating from NARAL and his vote to confirm Robert Bork in 1987, the man really has moderate views on, say, abortion and gay rights and wouldn't actually elevate Janice Rogers Brown to the Supreme Court. But, no. Even if McCain is a social moderate deep down inside (and I doubt it), the chance that he'll buck Brownback and friends on judicial nominees has always been unlikely. There's more.
