No, that would be a BIG step down for Hillary. Her ego couldn't take it. She used to be Queen Bee in that Hive, but under President Kerry (gag!) she would be just another worker drone. Imagine Donna Shalala with blonde hair--that would be Hillary. Plus a cabinet position would mean actual WORK. First Ladies and Senators can call their own hours. She couldn't stand it.
Heh,heh,heh--it ain't over till it's over!! The only thing you can trust Hilary on is that she will have her way, one way or another. I shudder to think of what she could do--it's scary!
