Okay, Help Me Out Here...
To the one-third of Hillary voters and one-quarter of Obama voters who say they'll vote for John McCain over the other Democrat:
Really? I mean, seriously? Do the math for me, here; you each support progressive candidates opposed to the Iraq War whose positions on most of the issues are virtually indistinguishable. Nevertheless, you'd rather give Dubya a third term than deign to vote for anyone other than your preferred nominee? You'd rather vote for the guy who has no problem keeping troops in Iraq for 100 years (or a million years)? The guy who thinks starting another pre-emptive war, this time with Iran, is a good topic for cracking jokes? A guy who lacks the political intestinal fortitude even to stand by his own immigration bill? A veteran who refuses to support other veterans? Really? That's who you want as President?
So, what's the deal? Are you nihilists? Political naifs? Or just incredibly immature?
