This is widely inconsistent with other polling data and doesn't make sense when you match it up with general election polling.
Huh? Most national polls have Trump leading by around 10 points, and he's up by about 10 points in actual votes so far.
I'm more talking about the favorability ratings, which really don't bear out, but the Democratic race is much closer than that. Of the states that have already voted, disproportionately southern, its 57-41 Clinton. It would make sense that when its all said and done its going to be more like 55-44 Clinton, so the 18 point gap is too large.
It's going to expand a little bit soon, especially after New York, Pennsylvania and Maryland vote. California, while being a state Clinton will carry, will probably narrow the margin a bit at the end because I don't think she'll carry it with 60% of the vote. Ultimately, I can see a 17-18% margin in the popular vote.
