What county in the nation had the biggest McCain / Obama split? The best I can find at the moment is my very own San Francisco
Barack Obama – 85% (198, 989)
John McCain --13% (30,888)
Can anyone find a bigger split? Let’s put a minimum of 2,000 votes on it, just for the hell of it.
Beaver County in Oklahoma went 89% for McCain, and plenty of other counties in OK can match the 85% split, and every single county in the state went for McCain.
