Consider the vote share of the two main nominees:
Take out the votes for Stein and Johnson, and one gets
Clinton 44/92 = 47.83%
Trump 37/92 = 40.22%
It's hard to see how Hillary Clinton is a particularly good cultural match for Georgia, but it is easy to see how Donald Trump, arguably the worst sort of city slicker possible, is a horrible fit.

Republicans have been doing very well in the South, so there's no room for Trump to improve...

Also, metro ATL has a highly educated population. The Republicans inside Atlanta voted Rubio strongly.
This map would probably explain Trump's support in Nevada as well, along with part of the Clinton trends in CO and VA.
To be fair, that map is as a share of Romney's white voters, but Nevada's college educated population is low compared to the national average. Clinton isn't really improving among whites there like in CO, VA, PA, etc. because of a lack of college educated whites, and Clinton's victory there will be mostly thanks to the African-American, Hispanic and Asian vote.
