(CNN) - Barack Obama did well with Democrats across both race and gender lines Tuesday night, and seems to be eating away at Hillary Clinton's backbone of support: women.
According to exit polls out of both Virginia and Maryland, in both states Obama won roughly 60 percent of the female vote - a demographic that has carried Clinton to success in past primaries.
Clinton fared even worse among men – more than two-thirds in both states chose Obama.
Meanwhile, the Illinois senator scored his highest percentage of African-American support to date - winning close to 90 percent of that voting bloc in each state. And the two evenly split the white vote in Virginia, while Clinton slightly beat Obama among the white vote in Maryland. In most past primaries, Clinton has held an edge among white voters.
Obama even beat Clinton among Latino voters, a group that has heavily favored Clinton in most past primaries. In Virginia and Maryland, Latinos went for Obama over Clinton by 6 points, though their support was not decisive in either contest – only 5 percent of Democratic primary voters in Virginia, and 4 percent in Maryland, were Latino.
The only demographic Clinton won was white women, who broke for her over Obama by 10 points in Virginia and 13 points in Maryland. But that margin is significantly smaller than the national average on Super Tuesday. She beat Obama among white women by 25 points then, according to national exit polls.
