@Farzad_MD yes -you may condition away relevant and important changes! i'm also worried that people may endogenously shift their responses (e.g., may have actually voted for candidate X last time, but report they didn't when surveyed today because they now find X repugnant).

No, a feature of a good poll is to provide independent information about public opinion. A poll isn't a model. It's *data*.
