The Oklahoma City results in Oklahoma County compared to Canadian County stand out immediately even from a basic Poly-Sci compare & contrast model.
It is also interesting that your data suggests that precincts located outside of OKC tended to vote slightly more Democratic than the County at large.... Sure these numbers most likely are minor variances, but still it doesn't really fit the CW and patterns of '16 PRES GE results.
I was going to point out that this broader observation broke my brain for a second. I was sitting there wondering "how can the non-OKC Oklahoma County precincts be more Democratic than the city proper?!", since Trump won the city by more than he won Oklahoma County. Of course, even though I knew Canadian County was skewing the results, it took me a minute to put it all together.
Based on the data, it would appear that non-OKC Oklahoma County voted for Trump by 19 (56-37), and OKC Oklahoma County voted for Trump by 4 (48-44), giving us the Trump win of 10.5 points countywide (52-41).
I thought the most interesting part was how closely OKC Canadian County resembled the remainder of Canadian County; the OKC portion was only about 1 point more Democratic than Canadian County as a whole. That just goes to show you how OKC isn't a real city by many standards (especially the portions in Canadian County). Even though it's only about 1/6 of the city's voters, they make the difference between a swing city and a pretty solidly-Republican one.
