Jackson, Mississippi (CNN) – It's unclear how Tuesday's GOP Senate race in Mississippi will end, but the race has no doubt been close–and ugly–in the final stretch.
With 87% of the state's precincts reporting as of 11 p.m. ET, state Sen. Chris McDaniel was narrowly ahead of incumbent Sen. Thad Cochran, 49.9% to 48.4%, according to numbers compiled by The Associated Press.
In Iowa, CNN projects state Sen. Joni Ernst, who garnered support from Mitt Romney and Sarah Palin, will win the GOP primary for the U.S. Senate seat.
Tuesday is the biggest single day of primary voting this year, with eight states holding contests from coast to coast. But the two races that are grabbing the most attention are the contests in Mississippi and Iowa.
Bixoli, Mississippi (CNN) - The Republican Senate primary race in Mississippi grew more intense Tuesday with the release of a new political ad, one week before voters head to the polls.

(CNN) - Police charged three more men in connection to the blogger who's been accused of taking a picture of Sen. Thad Cochran's wife in her nursing home bed and creating a political video against the longtime senator from Mississippi.
Authorities on Thursday arrested Mark Mayfield, an attorney and local tea party leader, and Richard Sager, an elementary school P.E. teacher and high school coach, according to The Clarion-Ledger newspaper. Police also charged a third individual, John Beachman Mary, but did not take him into custody because of "extensive medical conditions."
All three face conspiracy charges, the newspaper reported.

(CNN) - Two leading fiscal conservative groups are going after Thad Cochran, one of the most vulnerable Republican senators up for re-election.
Club for Growth and Senate Conservatives Action announced Monday they would each begin airing television ads against the Mississippi incumbent.
And Cochran's team is hitting back with an ad of their own, slamming GOP challenger Chris McDaniel for his views on government assistance programs and post-Hurricane Katrina disaster relief in the state. And Cochran is also getting assistance from an outside group as the ad wars in the Mississippi GOP Senate primary heat up.
(CNN) - While some Republican incumbents with primary challengers are trying to woo conservatives, Sen. Thad Cochran says he's not too familiar with the tea party.
"The tea party is something I don't really know a lot about," the six-term senator from Mississippi told reporters. "It's a free country. We have open opportunities for people to participate in the election process."

(CNN) - With the Supreme Court's ruling Tuesday on the Voting Rights Act, Mississippi and Texas announced they're ready to move forward with their controversial voter identification laws.
Eleven states in the past two years have approved laws that would require voters to show identification at voting booths. But Section 5 of the Voting Rights Act required some of those states with a history of voter discrimination to get "precleared" by the federal government before making any changes to voting laws.
