The Superstom Sandy arrived at an inopportune time (not that there is an opportune time) that affected voter turnout in the 2012 US presidential election. Esri has created a map that explores precinct-level data from the 2008 election overlaid on FEMA impact zones for the disaster. Darker shaded counties indicate areas that were most damaged by the storm.
