Before you believe a political, business or scientific poll, ask yourself: Who pays for, or sponsors it? That can affect the results.
Samples can be selected to give different results. Questions can be posed to produce preferred answers. Demographics can be altered to assure outcomes. And of course, interpretations can be subjective. Sponsorship can also influence the results of research. (See the Earl J. Weinreb NewsHole® comments and @BusinessNewshole at Twitter.)
