Mike Huckabee was likewise frolicking on Twitter, though he might be regretting his decision in the light of day, reports NBC News. "Racism exists because we have a sin problem in America, not a skin problem," Huckabee tweeted at one point. Then he followed up with this: "I trust @BernieSanders with my tax dollars like I trust a North Korean chef with my labrador!" After fierce backlash from users who said he was perpetuating a racist stereotype, he later added, "Poor liberals think it's racist to deplore a brutal dictatorship."
