Obama and Clinton supporters in Mississippi appear divided among racial lines.

(CNN) – Mississippi Democratic voters were sharply divided among racial lines in Tuesday's primary, exit polls indicate.

As has been the case in many primary states, Obama won overwhelming support from African-American voters. They went for him over Clinton 91-9 percent.

But Mississippi white voters overwhelmingly backed the New York senator, supporting her over Obama 72 percent to 21 percent.

According to the Associated Press, only two other primary states were as racially polarized — neighboring Alabama, and Clinton's former home state of Arkansas.

The exit polls also indicated roughly 30 percent of Mississippi Democratic voters said race was an important factor in their vote, and 60 percent of those voters supported Obama.

In Ohio, roughly 1 in 5 voters said race factored into their decision. Roughly 60 percent of those voters picked Clinton over Obama.

(CNN) — Are some of Mississippi's Republicans trying to cause mischief? Thirteen percent of the voters in today's Democratic primary identified themselves as Republican; they voted for Clinton, 78 percent to 22 percent. And 37 percent of the Democratic primary voters have a favorable opinion of John McCain; this group also went for Clinton, 62 percent to 37 percent.

Earlier this month, conservative radio host Rush Limbaugh told listeners that since the Republican race was all but over, they should turn out for Clinton, because of his view that she would be a weaker fall opponent for presumptive GOP nominee John McCain — but there is no statistical evidence to indicate his instructions played any role in the Mississippi results.

(CNN)– Early exit polls indicate the same distinct age gap in Mississippi that has appeared in many states this year: Barack Obama appears to garner the support of younger voters, while Hillary Clinton holds a greater appeal for older voters.

According to early CNN exit poll estimates, 72 percent of voters between the ages of 17 and 29 came out in support of the Obama, while 28 percent identified more with Clinton. For voters 60 and older, 53 percent said Clinton was fit for the presidency, while 46 percent weighed in for Obama.

(CNN) – Mississippi Democratic voters view Barack Obama more honest and trustworthy than Hillary Clinton, exit polls indicate.

Roughly 7 in 10 voters said Obama was honest and trustworthy, while only a little more than half said the same for Clinton.

But Clinton voters appear to view Obama in a more negative light than Obama voters view Clinton.

Greater than 9 in 10 Clinton voters said Obama was not trustworthy, while roughly 7 in 10 Obama supporters said the same of Clinton.

According to early CNN exit poll estimates, 56 percent of voters said the troubled economy was the biggest issue in deciding their vote. Fifty-four percent of those Mississippi residents cast their ballot for Sen. Barack Obama, 45 percent for Sen. Hillary Clinton.

Iraq and health care also registered as top issues for voters. Twenty-one percent thought the war in Iraq was the most critical issue facing the country, while another 21 percent felt that fixing nation's health care system was their number one concern.

(CNN) — One of the most Republican states in the nation takes center stage Tuesday in the battle for the Democratic presidential nomination.

Mississippi, which has not voted for a Democratic candidate in a presidential election in 32 years, holds a Democratic primary Tuesday.

With the campaigns of Sens. Hillary Clinton of New York and Barack Obama of Illinois battling for every delegate, the political spotlight is on a state not used to being the center of such attention.

JACKSON, Mississippi (CNN) — A few days after an aide to presidential contender Hillary Clinton accused her rival Barack Obama of behaving like Ken Starr, the Illinois senator kept up a recent string of counter-attacks, charging her campaign with strategically leaking a photo of him in African clothing and employing the “Republican playbook” in their effort to re-take frontrunner status in the Democratic race.

“When in the midst of a campaign you decide to throw the kitchen sink at your opponent because you’re behind, and you start — your campaign starts leaking photographs of me when I’m traveling overseas wearing the native clothes of those folks to make people afraid, and then you run an ad talking about who’s gonna answer the phone at three in the morning — an ad straight out of the Republican playbook — that’s not real change,” Obama told voters at a Mississippi campaign event Monday night.

The photo of Obama dressed in traditional local garb during a goodwill trip to Africa surfaced in the days before the critical March 4 contests. The Clinton campaign denied reports of any connection with its appearance, and Obama said at the time that he believed the New York senator’s assurances she did not know anything about the picture before it was published on the Drudge Report Web site the week before voters went to the polls in Ohio, Texas, Rhode Island and Vermont.

"…I take Senator Clinton at her word that she knew nothing about the photo. So I think that's something that we can set aside," Obama said at the Ohio debate late last month — a remark re-circulated by the Clinton campaign Monday night.

In a statement, the Clinton team attributed Obama’s Jackson remarks to his losses in last week’s primaries, and pointed to the Ohio comment, in which he seemed to absolve Clinton herself, though not her campaign, of responsibility for the photo’s distribution.

(CNN) – Barack Obama’s campaign has debuted a new radio ad in Mississippi called "Respect," highlighting what they call “derogatory” remarks Hillary Clinton made about the state late last year.

The ad also argues that Obama will “practice his Christian faith by respecting us” — an apparent push-back against the false Muslim rumors that have dogged him throughout the campaign.

In the 30-second spot, former Mississippi Governor Ray Mabus, an Obama supporter, derides Clinton for comments she made last fall singling out the state’s record of electing female politicians.

"I was shocked when I learned Iowa and Mississippi have never elected a woman governor, senator or member of Congress," Clinton told the Des Moines Register in October. "There has got to be something at work here. How can Iowa be ranked with Mississippi? That's not the quality. That's not the communitarianism, that's not the openness I see in Iowa.'"

Mabus accuses the Clinton campaign of calling Mississippi voters “second class.”

“Now I don’t know about you, but I’m tired of people putting us down,” Mabus says in the ad. “Tired of politicians trying to divide our nation instead of lifting it up.”

Mississippi voters head to the polls next Tuesday, March 11, with 33 Democratic delegates at stake.
