Clinton had hoped to pull off a win in Wisconsin. Instead, she lost ground on virtually every demographic, even white women, and actually lost to Obama among most major demographic groups except women.
Among independents, the key group that the presidential candidate must win, Obama pulled 62% to Clinton's 34%, among the 27% of voters who identified themselves as independents, according to CNN.
"The demographics -- poor, union, a lot of Catholics -- have all gone well for Hillary Clinton so far," said CNN senior analyst Jeffrey Toobin shortly before polls closed. "If she doesn't do well here, it shows her support is slipping away."
And CNN reported,in this article, Analysis: Obama continues to chip away at Clinton's base:
While Obama has been solidifying his base of younger, college-educated, higher-paid voters, he has steadily been chipping away Clinton's base of blue-collar, older, working-class voters.On Tuesday, Obama captured 53 percent of Wisconsin's white voters compared to 41 percent on Super Tuesday. He won 48 percent of women in Wisconsin compared to 41 percent on Super Tuesday.
He increased his standing with white seniors by 8 points, from 31 percent to 39 percent since Super Tuesday. He split the non-college-graduate vote 50-50 with Clinton compared to getting 42 percent of it on Super Tuesday.
Obama won almost half of the Catholic vote compared to a third of it two weeks ago, and he did the same thing with the rural vote.
He also seems to be taking the economy away from Clinton as an issue. He won 44 percent of those voters who said that was the most important issue for them on Super Tuesday, but he won 55 percent of those voters on Tuesday.
