Right. I think Hillary's best chance to win in '08 is with a credible third-party candidate splitting the Republican vote. That could happen with McCain or Rudy G getting the nomination....because a social conservative candidate will likely run and split the Republican vote, leading to a Hillary win.
The White House support for Arlen Spectre is ominous. If the social conservatives are betrayed on the one issue uppermost in their minds (abortion), they will not be gulled into supporting another RINO.
