Ask yourself this: if polls convinced you the Republicans had a better than even chance of winning this election and succeeding ones, would you change your political allegiances and join them?

Or, perhaps as a better example: should doctor's political action groups help fund politicians from Tobacco states which consistently vote *against* tobacco control if those same politicians also reliably vote *for* increased health insurance for the poor? Or should doctor's political action groups hold out for the perfect candidate?

That's the kind of practical dilemma we face all the time.
