Uh, basically, yes. Running the government by "polls" is pretty much BS. Since polls can be rigged, constrained by deceptive wording, and shopped to specific audience populations, they often don't represent reality.
"The remainder of 30% supporters are located on this site."
That's a bucketload of crap on general principals.
I must confess, I have been known to dump a little BS out from time to time.
