“Upstate South Carolina, dominated by Greenville, is not as conservative as you might think.”
What are you talking about? Trump got 60% of the vote in greenville county. Hillary 34%.
Your opinion is valued and your stat is correct. I also will acknowledge that the region is conservative as compared to say Asheville. Yet the electorate here keeps supporting the likes of Lindsey Graham and nominates Timmons. That shows me the area is drifting away from being right of center.
