Tierney Sneed for TPM:

Donald Trump is engaging in an unprecedented campaign of voter fraud fear-mongering. Not only is he putting Americans’ trust in the bedrock of U.S. democracy at risk, but what he has urged his supporters to do — in stump speeches across the country — would, if carried out, likely be a form of illegal voter intimidation.

Civil rights groups are already gearing up for an especially tense Election Day. Meanwhile, the federal government has been hobbled by a 2013 Supreme Court ruling in its ability to monitor elections in places with histories of voter intimidation. Of particular concern are states with loose open carry laws, where already, some armed Trump supporters have shown an interest in making their presence known at voting sites.
