Scalia & Thomas are the best two candidates.
And the "nuclear" option that the Administration ahs been too chicken-spit to use on the prior nominees WOULD be used this time.
One of those two men WILL be your next CJ.
I don't think so. One confirmation would be hard enough, two in a row would be a nightmare. Bush'll end up picking someone from the circuit courts I bet, like Posner or Easterbrook for example.
