Ryan Lizza declares victory and moves on:
Why then did the president break with most of his known habits and instincts last night? A few theories:
The Democrats’ strategy of unified opposition and obstruction may finally have chastened the White House. Democrats have recently made life miserable for Bush. They have killed Social Security and ground the rest of Bush’s domestic agenda to a halt. They have eaten up weeks of valuable time in the Senate with their opposition to lower court nominees. They killed John Bolton’s nomination to be ambassador to the United Nations. Democrats have been warned by Republicans that their obstructionism will cost them at the polls, but it may have forced Bush into choosing a more conciliatory nominee. If O’Connor had resigned immediately after Bush’s reelection one has to imagine that Bush would have picked a more mischievous jurist. So while conservatives are hailing the Roberts pick, it may actually be a sign of Bush’s current weakness.
Theres more, but you can read the rest yourself, if you want.
