This poll has some very odd crosstabs.
Yeah, like Clinton leads 51-38 among college-educated whites, while Trump leads 62-31 among non-college-educated whites. I would think that would be a much larger lead than 4 points.
Me too...college-educated whites vote at far higher levels. Each group makes up about 35-36% of the electorate. You would get a lead of Trump +10 with all white voters which make up 72% of the electorate. If Trump only wins white voters by 10 he's losing by far more than 4. Romney won white voters by 20 and lost by 3.9%
