The Results

Hillary had a chance to steal the nomination from Barack on Tuesday. That didn't happen.

At the same time, it wasn't really possible. Barack generally gets about 90% of the black vote, and North Carolina Democrats are 38% black.
According to exit polling in that state Tuesday, Obama won 92 percent of the black vote, which made up 33 percent of the total vote. He did equally well with black women and men, no less than 90 percent each.
What should scare the party is the lack of support for Barack among white voters:

....Hillary Clinton continued to firm up her advantage among whites in both states.

In Indiana, white men are going for Clinton 58 percent to 42 percent for Obama. In North Carolina, she was also winning among this group 54 percent to 40 percent for Obama.

Among white women, which made up 34 percent of the North Carolina vote, Clinton won 64 to 32 percent.
She could have come up with a decisive in Indiana, and that didn't happen. She won though, still somewhat of a miracle in a state, parts of which, are a suburb of Barack's home state of Illinois.

The numbers behind the numbers continue to be the devastating news for the Democratic Party. They will go into a general election with a nominee who can't win the support of working class voters.
The trend linking Clinton with white voters with no college degree seems to be continuing in Indiana, according to the polls. In Indiana, 65 percent of these voters went for Clinton, 34 percent for Obama. In North Carolina, 67 percent of these voters went for Clinton, 26 percent for Obama.
Are Democrats self-destructing by failing to consider giving the nomination to Hillary?Here's more proof that Barack is a niche candidate:

As for lower-income voters in Indiana, those making less than $50,000 a year are going for for Clinton by 51 percent, while 48 percent went for Obama.

But Clinton also won among higher-income voters, besting Obama 51 percent to 48 percent among those making more than $50,000.

Only 16 percent of Indiana voters said that race played an important role in their vote today, and of them, 57 percent said they went for Clinton, while 43 percent went for Obama.

And, as in previous primary contests throughout the country, older voters are so far going hard for Clinton. In Indiana, 7 1 percent of senior citizens went for Clinton, while 29 percent went for Obama.
