It is becoming clearer as the final results trickle in that Clinton won the election - but the distribution of votes was uneven. Her margin in the popular vote is greater than the sum of her losses in the swing States, which were all in the 1% range. What is clearest is that Trump didn't so much win, as Clinton lost because turnout was lower than expected in the groups she needed to win. She is correct that Comey's letters were sufficient to drive down participation by a percentage or so. Certainly enough.

But what is most frustrating (to me), and empirically demonstrable, is that voter suppression efforts in North Carolina, Wisconsin, Ohio and Florida were successful.

The low turnout for Clinton had little to do with her black support and everything to do with the effective campaign of voter suppression run by Republicans, one that has decimated accessible options for people of color. This election illustrates the importance of alternatives to the current voting system, which continues to actively disenfranchise marginalized populations subject to numerous barriers to entry. It’s time to update the ballot box to make sure everyone’s voice is being heard.

Wisconsin turnout plummeted to its lowest point in 20 years in the first election where voters were required to present an ID to vote. Trump won the typically presidential blue state by just over 27,000 votes. Wisconsin’s elections chief told The Milwaukee Journal Sentinel he believed voter ID depressed turnout in high poverty wards, as the City of Milwaukee saw 41,000 fewer votes.
Election Results 2016: Did Voter ID & Voter Suppression Help Elect Trump?

After the Supreme Court struck down part of the Voting Rights Act in 2013, many polling places were closed across the country. According to the Texas Tribune, five of the top 10 counties nationwide for closing polling places were in Texas (where Clinton had a late surge but Trump easily carried in the end). The court ruling invalidated a provision that made it tougher for some states to enact laws that restrict voting.
This, I think, is the biggest issue facing the country in the next 2 years.

A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
