She definitely won Norman. Perhaps Stillwater or OKC but I doubt.
OKC was the biggest city in the country that Trump won.
Do we have a definitive source on this?
I've heard a few people repeat this on Atlas, but not yet seen anyone that has actually run the precinct numbers on OKC for the 16 Pres GE.
This site:
https://decisiondeskhq.com/data-dives/the-largest-city-to-vote-for-donald-trump/that someone posted on the largest cities by state to vote for Trump thread, shows the numbers for Jacksonville, FL and Fort Worth, and approximates OKC by saying "over 40,000 votes".
They also claim that Mesa, AZ is confirmed for Trump, but they don't give numbers and just say that non-Phoenix Maricopa was heavily Repub, but it might be worth checking as Mesa has a lot of Mormons who may have defected to McMullin.
