Grammar Resistance Leader, TLA Dictator
Telling people it is more moral to vote according to one principle over another is morally desolate.
I think you're speaking with the sensibilities derived from being part of a parliamentary system. The parties MUST stand for something in that system. Ours is turning into stricter party lines and ideology, but the idea that you vote for the person and not the party is pretty deeply entrenched in America.
In Canada or the UK, a party leader generally stands for the party principles. Yeah, they can rewrite those principles somewhat, but nothing like the US where the winning candidate can (and often does) simply ignore the planks of the platform agree upon at his own nominating convention. I'd bet that if a questioner worded the question deviously enough, you could get either major candidate to disagree with the platform in the first Presidential Debate, usually within 3/5 weeks of the second convention. I'm pretty sure they barely read the thing.
