Not concerned...these numbers are very satisfying but polls today are in many ways...junk. Most polling outfits only use landline phones. More and more people do not have landlines and with caller ID and norobo many who do choose not to answer. Now this affects both right and left. The snowflake millenials with their iPhones and the Freepers who pick up the landline only when they know the caller. So this poll isn’t IMO suspect because Trump is doing well. It’s just suspect.
Actually, all polls now include cell phones.
