Polls are snapshots that reflect opinions at one instant in time.

That is precisely what I'm getting at -- or what I'm doubting, to tell
the truth. I've never seen anything to substantiate that the polls have
any value, other than to give the media something to talk about as if
they had "authoritative" information -- yes, I'm laughing -- and to give
politicians a compass to pose on.
