While the first Democratic debate was in full swing, candidates Hillary Clinton, Bernie Sanders, Lincoln Chafee, Jim Webb and Martin O'Malley were addressing tough questions about systemic racism, incarceration rates and inequality.

While they were doing that, the Twitter account of Republican candidate and former Arkansas Gov. Mike Huckabee was busy sending a racist joke about Asians, just minutes after claiming the United States has a "sin problem," not a "skin problem."

The joke was bad for more than one reason: Reporter Adam Weinstein pointed out that Huckabee's son David Huckabee once killed a dog while working as a counselor at a Boy Scout camp, earning his termination.

According to a Real Clear Politics average of polls, Huckabee is currently tied for eighth place in the GOP primary, with the support of 2.7% of GOP primary voters alongside Kentucky Sen. Rand Paul.
