The Roberts Choice - A Stroke of Genius?

The speculation today has been that a female jurist would be named to replace Justice O'Connor. It has been assumed that would be the safe pick. However, the President has just announced John Roberts as his choice. From what I hear, he should be a fine choice and is widely respected on both sides of the aisle.

I think it may be a strategic stroke of genius. If Schumer, Durbin & Company try to block Roberts with a filibuster, it will likely fail. If they accidentally do the smart thing and save the filibuster option for Rehnquist's replacement, the President can then choose a female jurist for Chief Justice which will be impossible for them to filibuster. The majority of the Dems will not want to be seen as blocking the first female Chief Justice. Checkmate.
