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