Hillary Clinton's favorable rating has fallen below 50 percent for the first time since she last ran for president eight years ago, according to a Washington Post-ABC News poll released Thursday.

In the survey, 49 percent of respondents said they viewed Clinton favorably, while 46 percent said the opposite. Two years ago as Clinton prepared to leave the State Department, her popularity peaked with about two-thirds of Americans viewing her favorably.

That said, Clinton still crushed by double digits every Republican tested against her in the poll's hypothetical 2016 contests. In the closest race, she topped Jeb Bush — whom a majority of respondents viewed unfavorably — 54 percent to 40 percent.
