Presidential election results, 1936-2016
How did Orange County vote in the past two elections?
While Republicans won Orange County by 6 points in 2012, the county's shifting demographic makeup led to shrinking margins of victory. Democrats won handily in many of the most populous cities. While traditionally Republican strongholds ultimately delivered Orange County to Mitt Romney in 2012, Democratic inroads expanded in 2016, allowing Hillary Clinton to win.
Voters in areas with lower household incomes and higher percentages of minority voters voted decisively for Barack Obama in 2012, and voted in even higher percentages for Hillary Clinton.
