Kansas was won by Republican nominee John McCain by a 14.9% margin of victory. Prior to the election, all 17 news organizations considered this a state McCain would win, or otherwise considered as a safe red state. He won all but three counties and one congressional district in the state. Obama still performed significantly better than Kerry, and his 41.55% of the vote remains the highest for a Democrat in the 21st century, although his running mate Joe Biden nearly matched that percentage 12 years later, with a slight reduction in margin of defeat.
As of 2024, this is the last time that Crawford County voted for the Democratic candidate in a presidential election.
