Tom Goldstein predicts that Obama will nominate Elena Kagan for the Supreme Court.

He'd already predicted it, and he still thinks so:

It seems clear to me that none of the three nominees—including even Diane Wood—will generate a knock-down, drag-out fight in the Senate. In effect, the White House preempted the prospect of an all-out war by not including the leading liberal prospects in its published short list of finalists. The Bush White House took a similar approach when it nominated the conservative Samuel Alito, but passed on then-Fourth Circuit Judge Michael Luttig, to whom Democrats had signaled their very strong objections....

More surprising, institutional Republicans have not been particularly vocal in their objections to the potential nomination of Diane Wood. Judge Wood’s abortion-related opinions would mean that she would receive only in the range of 55 to 60 votes. But confirmation would still be all but assured....

It is ... true that Judge Wood is the nominee whom progressives would prefer to see nominated, by an order of magnitude. While criticism from the left of General Kagan (who as the perceived front runner has received the most attention) and Judge Garland has been limited to a few, very vocal liberal commentators, it nonetheless exists.... So to the extent that Wood presents the potential downsides of some fight in the Senate and mobilizing conservatives in the election, she has the upside of appealing to and mobilizing core constituencies of the president....

On the ability of the three to persuade a conservative member of the Court such as Justice Kennedy, all have significant strengths as well.... Diane Wood is not only personally charming but has gone toe to toe with Judges Easterbrook and Posner and persuaded them on significant issues. Elena Kagan has significant demonstrated success in working with conservatives at Harvard Law School, which is an exceptionally challenging environment, and has parallels to the relationships at the Court. But she has never been a judge, and would as a consequence presumably take longer than the others to adapt to the new role.

I don't quite get it. Why won't Obama give liberals what they want? The strongest argument for Kagan over Wood seems to be age. Kagan's 49. Wood is 59.
