Today, Mississippi holds its presidential primary.
The state's large black electorate makes it fertile ground for Barack Obama. And it's another chance for Obama to ease the sting of losses last week to Hillary Clinton.
In Mississippi, Barack Obama accused Hillary Clinton of trying to “bamboozle voters” with talk of a joint ticket.
"I am running not for Vice President. I am running for President of the United States of America,” says Obama
It was an emphatic no to Clinton's hint she'd pick him as her running mate. Obama's made no such invitation back, if he's the nominee. Advisers said they can't imagine it.
"I don't think Senator Clinton represents the kind of change that's needed."
In Pennsylvania, Clinton suggested talk of teaming up is overblown
"I'm looking forward to getting the nomination and it's premature to talk about whoever might be on whose ticket,” Says Clinton.
She said a Clinton–Obama dance card is something many democrats want.
Clinton is hopeful Pennsylvania will be her next boost.
“You know Governor Rendell and I hear people sometimes saying, 'Well, we don't want to go back to the 90s,' and I'm saying, 'Well, what part of the nineties don't we want to go back to, peace or prosperity? Which one?'" asks Clinton.
Today's contest in Mississippi is expected to widen Obama's delegate lead, but not by much.
Thirty–three delegates are at stake, allocated proportionally. By midday both democrats will be in Pennsylvania: Obama looking to chip away at Clinton's support ahead of that primary next month.
Today's primary is the last before the democrats settle into a six week battle for Pennsylvania.
