I expect Bush to name nominee tomorrow or Monday. And if/when the Chief Justice resigns, that name will come almost immediately.....unless he dies suddenly, which of course will lead to an appropriate mourning period prior to the naming of a replacement.
If Hillary is involved in the situation, Rehnquist might die suddenly...like the rest on the Arkancide list.
Another scenario:
He probably saw Felos in the hospital and wheelied it outta there.
