I understand that on some social media sites, Trump's victory is being blamed on Southern states closing black precinct polling places, so blacks couldn't vote. This seemed implausible, and should generated a storm of lamestream media whining. What I found was this story http://www.commondreams.org/news/2016/11/04/voting-rights-protections-gutted-polling-places-shuttered-massive-scale about how expiration of the Voting Rights Act allowed state and local governments to consolidate and reorganize precincts without federal supervision. There was no closing of polling places on Election Day; these stories are from before Election Day.
Of course, you could find out where your polling place was with a phone call, but that would require you to care. Black voting was down from 2008 and 2012 because there was no black man running for President. The progressives just don't like admitting their voting base is racist.
