Bernie Sanders was only able to win the support of one major demographic on Super Tuesday, according to exit polls presented by MSNBC's Steve Kornacki. While Hillary Clinton dominated among black voters (83 percent to 15 percent) and Hispanics (67 percent to 33 percent), Sanders' sole group win was with white men, 54 percent to Clinton's 44 percent.

Clinton has a lot of thanks to give especially to black voters, NBC News reports. NBC writes that, "If only white Democrats had voted on Tuesday in [the Southern] states, Vermont Sen. Bernie Sanders would not have been that far behind Clinton in terms of accumulating delegates."

Sanders has been criticized for his concerning lack of appeal among minority voters as well as for his attention-grabbing "Berniebros," who tend to identify as exactly the demographic Sanders won over on Tuesday — white men. "The Berniebro is someone you may only have encountered if you're somewhat similar to him: white; well-educated; middle-class (or, delicately, 'upper middle-class'); and aware of NPR podcasts and jangly bearded bands," The Atlantic writes.

And while Sanders has surprised in the past by ranking well with a group Clinton desperately wants — millennial women — he actually lost women overall to Clinton, with white women favoring her 57 percent to Sanders' 41 percent in the exit polls. White voters as a whole also gravitated toward Clinton, 50 percent to 48 percent. Jeva Lange
