In the 2008 presidential election, the majority of Northern Virginia voters voted for Democratic presidential candidate Barack Obama. Over 70 percent of registered voters in Arlington, Alexandria and Falls Church voted for Obama. Fairfax County, Loudoun County, Manassas and Prince William County also went to Obama, with Obama receiving 60 percent of the vote in Fairfax County compared to Republican candidate John McCain's 39 percent. Obama's win in Fairfax County, the most populous county in the state, marks the second time a Democrat has carried that county since the 1964 breakdown of Democratic predominance in the South (the other being the 2004 presidential elections when the county went to John Kerry). Obama's victory in Northern Virginia continues the trend of Northern Virginia favoring Democrats over Republicans.
