Presidential elections
At the national level, James City County has been a Republican-leaning county in presidential elections for decades, although as the county grew in the 2000s it began to trend Democratic and recent results suggest the county may soon become more of a purple county than a solid red one.The county has not voted Democratic at the presidential level since delivering a plurality win to Hubert Humphrey in the 1968 election.
