There's an old (and possibly accurate) adage that "A Government does not survive long without a healthy opposition", and I suspect this applies within a Party as well. (The (radical) NeoCons have not had a strong & healthy opposition from conservative Republicans (or Democrats *sigh*) for something like twelve years, and I think the results are showing. I think it was someone named Aberthnot who said something like "All political parties die, eventually, from swallowing their own lies".)

It seems to me that continuing opposition between the Democratic candidates could be a fine thing -- _if_ they'd concentrate almost entirely on their different approaches in matters of Policy & Implementation, and reserve their actual Attacks for McCain and established Republican Policy as it has been manifested (i.e., often the precise opposite of the Official Republican Platform & Selling Points).

If pressed, I'd have to say that it seems to me that Clinton has been a bit less good about this than Obama. She's demonstrating that she's strong, aggressive, and determined (all qualities we need in a President now) but I think maybe she's lost track of the idea that it's not smart of alienate anyone unnecessarily, and that the Really Crucial thing is not that she be nominated, but that The Democrats Win Big in November.
