• All states bordering West Virginia voted Democrat.
• All states whose names are the end of another state's name voted Democrat.
• Among Wyoming's neighbors, the delegate counts for the Republican states and the delegate counts for the Democratic states both form 3-term arithmetic progressions, and Wyoming itself voted the same as the progression with the larger common difference.
• California, Texas, and all of New England went in the opposite direction of how they've gone in the past 12 years.
• Everywhere that Marco Rubio won during the 2016 primaries voted Republican.
