Chris McDaniel, a state senator from Mississippi and primary challenger of GOP Sen. Thad Cochran, has already gotten into some trouble for hanging out with neo-Confederates, but according to a report from Talking Points Memo, it would appear the blowback wasn't sufficient to put McDaniel off the practice altogether.
Per TPM's report, McDaniel's Twitter account (which is unverified but frequently tweets material suggesting it is being run by McDaniel or a member of his team) retweeted on Sunday a message from RRSmith #WR (@rrsray) urging others to support the Tea Partyer and former radio host's campaign. Here's a screen shot from TPM:
The @rrsray Twitter bio describes the user as "Nationalist, staunch proponent of 2nd & 10th Amendment, GoldenDawn & Southern Nationalism." (Golden Dawn is a greek neofascist party, recently embraced by many political white supremacists in the U.S.)
A better sense of @rrsray's political racism, however, can be found by perusing their tweets, which are frequently and unsubtly bigoted. @rrsray tends to retweet the most virulently racist material (which we'll spare you) but their racism is nevertheless apparent:
The most recent poll we could find of the race between Cochran and McDaniel shows the latter trailing by more than 20 points.
