“In the 2012 election, there were only 275 counties – less than 9% of all counties and county-equivalents in the nation – in which fewer than 5 percentage points separated Democrat Barack Obama and Republican Mitt Romney, according to a new Pew Research Center analysis of county-level voting data. That was the fewest closely contested counties since Ronald Reagan’s landslide re-election in 1984.”
