The "Wait and see" policy that has gotten more politicians not commit citing the need of more "knowledge" of the situation is a tried and true montra for all politicians.
Now look, Blagoevich went ahead and nominated Burris and there was nothing Reid or any other senator could do about it. Their hands were tied b/c they didn't want a state wide runoff, possibly allowing a repub to take the seat.
Sometime it might be necessary to take your political book back out and restudy the first chapter.
Now Reid looks weak wehn it comes to these things and will have a harder time next time.
