Hey, Flanders, the first George Bush distanced himself from Reagan. Al Gore distanced himself from Clinton. There are few very presidents who leave as unqualified successes. Reagan is a good example. Lots of people whitewash his presidency, but when he left office, Iran Contra was a big deal and it was probably smart strategy to build space from that record.
Marilyn, I do not believe that at all. She still has big support within the party and she's probably the person best able to raise lots of money. And, again, once a person wants to be president, he or she will ALWAYS want to be president.
She's running.
BTW, her actions telegraph this. She will leave the cabinet in December, win or lose, because that's what people who want to run for president do. And she's basically saying that right now.
