I don’t see an issue with early voting yet. Absentee voting is a little more problematic. At this point, the Republicans look like they had a lead of 40,000 or so in 2012. In 2016, the lead looks like about 20,000 or so. Romney won NC by about 100,000 in 2012.
I live in the suburbs of Forsyth County, outside Winston-Salem. Obama won Forsyth County with 53% of the vote. I don’t drive that frequently in Winston-Salem neighborhoods.
It is hard to gauge the enthusiasm for either Clinton or Trump. In 2012, I saw a fair number of cars with Obama bumper stickers. I don’t think I have seen a single car with a Clinton bumper sticker. I have seen exactly one Clinton yard sign. One the other hand, I see a fair number of Trump yard signs/bumper stickers but not as many as Romney.
