Hillary Clinton's unpopularity rating is rising among her core supporters

Hillary Clinton's negative ratings hit a new high in an ABC News/Washington Post poll released Wednesday, and it looks like she might be in trouble even among her core supporters.

For the first time in a year, most women surveyed in the ABC News/Washington Post said they view the Democratic presidential nominee unfavorably. Last month, 54% of women said they viewed Clinton favorably, but in the new poll, that figure has dropped to 45%.

And it's not just women.

Sixty percent of highly educated voters (those with post-graduate degrees) said earlier this month that they viewed Clinton favorably. That figure has now plummeted to 47%.

Her support among moderates also dropped, which perhaps isn't shocking, but she also saw a significant decrease in support from liberals. Her favorability rating among that voter base fell from 73% to 62%, which ABC News/Washington Post attributes to a drop among Hispanics.

Clinton's opponent, Republican presidential nominee Donald Trump, also has high unfavorability ratings - 63% of those surveyed said they viewed Trump negatively. Clinton and Trump are now the most unpopular presidential candidates in more than 30 years of polling, according to this survey.

Overall, 56% of those in the ABC News/Washington Post poll said they viewed Clinton unfavorably - an increase of six percentage points in three weeks. Among registered voters, Clinton's negative rating rises to 59%.

The spike in Clinton's negative ratings come as she battles the perception that she gave special access to Clinton Foundation donors during her time as secretary of state.
