According to early CBS News exit polls, the economy was the most important issue on the minds of Democratic voters in Mississippi. This has been the case throughout the primaries.
More than half of Democratic voters cited it as their number one issue, and almost nine in ten said they believe the U.S. economy is in bad shape.
Also, according to the exit poll, a majority of Democratic voters in Mississippi thought favorably of the two Democrats running together in the general election campaign. Fifty-seven percent said that they think if Clinton is the eventual Democratic nominee, she should pick Obama as her vice presidential running mate. And 55 percent say that if Obama is the eventual Democratic nominee, he should pick Clinton as his vice presidential running mate.
However, Democratic voters do have strong opinions about who should be at the top of the ticket, according to the exit poll. More than half of Obama voters said they would not be satisfied if Clinton was the nominee. And more than seven in ten Clinton voters said they would not be satisfied if Obama was the nominee.
Mississippi's large black electorate in Tuesday's voting makes it fertile ground for Obama, who has swept the other Deep South states and has pulled huge margins among black voters. Clinton, the New York senator and former first lady, campaigned in the state last week, but by Monday was in Pennsylvania, where the primary is April 22.
Obama, making a final stop Tuesday morning in Greenville before flying to Pennsylvania, noted that the Mississippi delta area is struggling economically.
"We just haven't seen as much opportunity come to this area as we'd like," he told a small gathering at Buck's restaurant. "And one of the challenges, I think, for the next president is making sure that we're serving all communities and not just some communities."
He then ordered eggs "scrambled hard," with turkey sausage, wheat toast and grits.
The Illinois senator spent all of Monday in Mississippi, drawing enthusiastic crowds in Columbus and Jackson, the capital. At stake are 33 delegates and another chance for Obama to ease the sting of last week's losses to Clinton in primaries in Ohio, Texas and Rhode Island.
In Lowndes County, Miss., Circuit Clerk Haley Salazar said Tuesday there appeared to be good early participation at the polls despite wet conditions.
Obama's visit on Monday "spurred a lot of interest here. We've had a lot of people coming in and asking about registering to vote ... and we have a a lot of calls," Salazar said.
With Clinton's camp saying she has little chance in Mississippi, the campaigning here focused largely on national issues.
Obama used his Monday morning visit to Columbus to try to squelch speculation that he might accept the vice president's slot on a ticket headed by Clinton. He noted that he has won more delegates, states and votes than Clinton.
"I don't know how somebody who is in second place is offering the vice presidency to the person who is first place," Obama said, drawing cheers and a lengthy standing ovation from about 1,700 people. He added: "I am not running for vice president. "I am running for president of the United States of America."
Later, at a rally in Jackson with 9,000 people, Obama painted Clinton as part of the Washington establishment whose time has come and gone.
The nation does not need "the same old folks doing the same old things, talking the same old stuff," he said, essentially lumping Clinton with President Bush and Republican candidate.
He accused Clinton's campaign of leaking a photograph of him wearing traditional African garments, including a turban, during a visit to Africa. That was "straight out of the Republican playbook," Obama said. "That's not real change."
Clinton has said she is not aware of anyone on her staff leaking the photo.
For her part, Clinton had moved on to Pennsylvania, where she held a rally in Scranton and carefully sidestepped questions about the sex scandal threatening the political career of Eliot Spitzer, her home state governor and political ally.
"I don't have any comment on that," she said when asked about reports that Spitzer allegedly paid for sex with a high-priced call girl at a Washington hotel. "Obviously, I am sending my best wishes and thoughts to the governor and to his family," Clinton said.
Obama's two Mississippi events on Monday drew heavily black audiences that cheered him unabashedly.
"I'm here because of the electricity, the energy that seems to form around Barack Obama," truck driver Jasper Clark, 53, said in an interview before the Jackson rally. "It inspired me, and it's been a while since I've been inspired politically."
Clark said Clinton "is a nice person," but among his friends and acquaintances, "I'd say it's an 8 to 2 ratio" for Obama.
