Ugh. Sometimes I hate being so right.
Though I don't take this response as indicative of much else, I still can't help but ask: why?
Why would you refuse to support the winner of a primary that you, yourselves are competing to win? Surely there's more that's drawing you to the party besides Obama's magnetism? For instance: perhaps you share the same values that drew Obama himself to the party in the first place. Those values, incidently, are probably the same ones that drew Clinton to the party.
Also, what makes you think that a Clinton-lead Democratic Party would be so antithetical to your interests, values, and views than an Obama-lead one? Clinton and Obama have worked together on legislation and (despite the rhetoric) agree on most key issues, albeit differing on specifics. There's also more to the party than the position of the President. A Democrat in the White House means like-minded appointees to the Supreme Court, the rest of the justice system, hell, the entire bureaucracy! I admit that depending on the Republican candidate some right-leaning Dems might have a legitimate case for jumping ship, but Obama really isn't attracting those votes: he's a lefty. Presumably as supporters of a lefty, you don't want a party so captive to the right to retain power. I find it confusing, then, that you wouldn't go for Clinton considering your options.
Guess I just needed to vent.
Before the primaries began, I would have agreed with you. However, since then the Clinton campaign has smeared and lied about Obama in ways that would Karl Rove blush, and there is no way on Earth I am going to root for such a candidate. But that's my prerogative.
Not that it matters from my side, seeing as can't vote, but I know plenty of US-based Obama supporters who share that view. A lot of them will be inclined to sit out the election if Hillary wins the nomination.
