WASHINGTON - Mississippi earned Barack Obama his second victory in two weeks, winning the Democratic primary in a blow-out: 61 percent to Hillary Clinton's 37 percent.

Black voters put Obama over the top, with nine in 10 African Americans favoring Obama over Clinton.
But race isn't just playing out in the polls. It's also spilled onto the campaign trail's war of words.
One prominent Democrat - Geraldine Ferrarro, the 1984 vice-presidential nominee, told a California paper that "if Obama was a white man, he would not be in this position. And if he was a woman, he would not be in this position. He happens to be very lucky to be who he is."
That led to calls for Ferrarro to be fired from the Clinton campaign.
Ferraro responded harshly.
"They better just lay off me. I'm outraged that they would think I'm racist - absolutely outraged," she said.
Obama called Ferraro's comments about him "absurd" and "divisive," "having no place in politics or the Democratic party."
Clinton quickly distanced herself from Ferraro's remarks.
"Well, I don't agree with that and I think it's important that we try to stay focused on issues that matter to the American people. Both of us have had supporters and staff members who've gone over the line and we have to reign them in and try to keep this on the issues," she said.
Next Stop: Pennsylvania
While the back and forth continues, both candidates are looking ahead to Pennsylvania, where 188-delegates are at stake in the state primary on April 22.
Clinton trails Obama in overall pledged delegates by about 100, but polls show she maintains a strong lead among Democrats in the Keystone State.
As things stand now, neither candidate can clinch the nomination without the support of superdelegates.
So both Clinton and Obama are entrenched in a vigorous race for the backing of those party leaders sooner rather than later to avoid a brokered convention, which Democrats want to avoid out of fear it could cripple the party heading into the general election in November.
