Any poll showing both candidates below 45% is ridiculous, but of course the Trump fetishists will pounce on this.
But not the ones showing Trump below 40% in VA, WI and PA?
I've never mentioned Trump polling below 40% in PA, though he does struggle to break it in VA. Trump has been getting destroyed in WI polling since he began his candidacy. Trump's poor numbers in those states are stable, no reason to disbelieve them. Hillary has consistently polled above 45% in almost every national poll (except for the widely discredited Rasmussen one). So there's no reason to take this poll seriously, everyone who isn't a Trump fetishist would admit her numbers are too low here (as are Trump's, imo).
