While PJ's answering that, some of us would like to know why it is. Nothing has changed tactically, except the GOP now has three judges getting confirmed.
Strategically I'm concerned with the GOP angering its base, but that's a larger issue than just this particular deal (which does serve as a powerful catalyst, however).
Here's why...the Pubbies still think the senate is the local country club-where rule changes can be debated for months and years on end, clever wagers and per hole bets being part of the pleasure and enjoyment of such. The Democrats all play politics like they're born in Hell's Kitchen. Were the Democrats in the same position, and Reid or Daschle the majority leader, this nonsense would have been done and over by 9:01 am January 21st, and the President's nose rubbed in it for the next weekby the MSM, and Hillary Clinton the next Chief Justice by noon.
