There is no good answer to that, which is precisely why the current controversy and this thread exist. Can we in good conscience sacrifice the principles in question which conservatives hold dear and Giuliani does not, in favor of the overall practical objective of avoiding another Clinton presidency? And if we do, what price will we pay for it? And if we don't, what price will we pay for that?
Broadly speaking, when in doubt, go with principle, because that's what principles are for. I think what bothers a lot of people is the prospect of a general election wherein those principles are already lost no matter which way we vote. That's what this ruckus is all about. IMHO, of course.
Dang. You’re hitting on all eight cylinders!
