Somebody! will only enter if the polling shows that she could win. The dims have a very early primary, which could cause problems. It's definitely not between Somebody! and the dims, but more between Somebody! and GWB in November. Unless it is clear that sho would prevail in November, she will not accept the dimo nomination, and thus they will announce a sacrificial candidate -- Kerry, Edwards, perhaps Daschole or even Lieberman.
Agreed. And this is another reason that it is in her interests for there to be a crowded Democrat primary where no clear consensus candidate emerges.
She can then determine whether she wants in, based on how she feels her prospects would be. See, she has never taken a risk in her life and she is not about to take one now. If things work out for her, she can get the rat nomination without ever having to take the risk of entering a primary!
If the prospects of beating Bush remain dim, then she simply keeps her head down and lets one of the other chumps get sacrificed. That way she can never be branded a loser since she never said she was "in" to begin with. No risk.
