* Why are we so confident these are the most detailed maps you’ll ever see from the 2014 Senate elections? Precincts are the smallest level of geography for publicly-reported election results. There were more than 175,000 precincts in the United States in 2012, fifty times the number of counties. The maps here show precinct-level results, where available, from some of the closest Senate races.

Notes

Maps exclude early votes in counties that do not report them by precinct. Some precinct boundaries are approximate.
