As we first heard from two TPM readers early this afternoon, a White Nationalist Super PAC (yes, that's now a thing) is now blanketing Iowa with Robocalls on behalf of Donald Trump. And for bonus awful, the leader of the organization is the man Charleston Massacre shooter Dylann Roof cited as inspiration for his killings in his manifesto. As the audio puts it, "We don’t need Muslims. We need smart, well-educated white people who will assimilate to our culture. Vote Trump.” Details and audio here.
