Bernie Sanders' biggest fans aren't middle-class Americans. Though the socialist senator might be campaigning to end the war on the middle class, a new ABC News/Washington Post poll out Friday reveals that the group Sanders is polling the best with is those who earn $100,000 or more annually — and he polls the worst with middle-of-the-road earners.

Sanders wins the favor of the top-tier earners 48 percent percent to 38 percent — his widest winning margin across groups including those earning less than $50,000 and those earning between $50,000 and $100,000. Among the middle bracket of earners, Sanders is viewed more unfavorably than favorably, 39 percent to 46 percent. And among the lowest earners, Sanders wins favorability by a slim four-point margin, 40 percent to 36 percent.

Hillary Clinton, on the other hand, polls best among those who earn less than $50,000 annually. She wins the favor of that group 53 percent to 44 percent. In the other two categories though, the negative views outweigh the positive. Clinton's rating is 40 percent favorable to 59 percent unfavorable in the $50,000-$100,000 bracket, and 45 percent favorable to 55 percent unfavorable among those who earn $100,000 or more.

The survey's margin of error is plus or minus 3.5 percentage points. Becca Stanek
