WASHINGTON (AP) -- In a remarkable political turnaround, six-term Sen. Thad Cochran of Mississippi edged out tea party-backed challenger Chris McDaniel Tuesday night in a bruising, costly Republican runoff that pitted Washington clout against insistence on conservative purity.
With 99 percent of precincts reporting, Cochran had 51 percent to McDaniel's 49 percent, three weeks after McDaniel had beaten the veteran lawmaker in the initial primary round but had fallen short of the majority needed for nomination. In the three-week dash to the runoff, Cochran and his allies had highlighted his seniority while McDaniel had argued that Cochran was part of a blight of federal overspending.
In a brief speech to supporters, Cochran thanked those who helped him secure a "great victory. ... It's a group effort. It's not a solo. And so we all have a right to be proud of our state tonight."
A defiant McDaniel offered no explicit concession, but instead complained of "dozens of irregularities" that he implied were due to Cochran courting Democrats and independents.
"We are not prone to surrender, we Mississippians," McDaniel told his backers. "Before this race is over we have to be absolutely certain the Republican primary was won by Republican voters."
The win for Cochran, a stalwart of the Senate Appropriations Committee, was a fresh blow to the tea party movement, which spent millions to cast aside a mainstream Republican who won a U.S. House seat in President Richard Nixon's GOP wave of 1972 and has served in the Senate for more than three decades.
In another setback for the tea party, two-term Rep. James Lankford of Oklahoma won the GOP nomination in the race to succeed Sen. Tom Coburn, who is stepping down with two years left in his term. In the solidly Republican state, Lankford is all but assured of becoming the next senator. Part of the House GOP leadership, Lankford defeated T.W. Shannon, a member of the Chickasaw Nation and the state's first black House speaker, backed by former vice presidential candidate Sarah Palin and Texas Sen. Ted Cruz, two stalwarts of the right.
Despite Congress' abysmal public approval ratings, incumbents have largely prevailed midway through the primary season -- with two notable exceptions.
Little-known college professor Dave Brat knocked out House Majority Leader Eric Cantor in Virginia's Republican primary this month, and Republican Rep. Ralph Hall, 91, lost in a Texas runoff to a younger Republican.
Cochran and his allies, notably former Gov. Haley Barbour, promoted his Washington establishment credentials, focusing on the billions he funneled to his home state, one of the poorest in the nation. In a last-ditch effort, Cochran reached out to traditionally Democratic voters -- blacks and union members -- who could cast ballots in the runoff. That possible factor in Cochran's victory is sure to be cited by critics in days and weeks to come.
In predominantly black neighborhoods of Hattiesburg's south side, an organized effort for Cochran was evident. Ronnie Wilson, a 50-year-old unemployed Hattiesburg man, said he had been encouraged by his pastor to vote for Cochran.
"They say the other guy is trying to cut food stamps and all that," Wilson said. "I'm trying to look after the majority of people not working."
McDaniel had railed against the federal "spending sprees" by Cochran, but his calls to slash the budget unnerved some voters.
Frank McCain, a 71-year-old retired tax administrator from Mendenhall, voted for Cochran.
"I believe he is doing a good job," McCain said. "But mostly I'm more scared of the other candidate. He wants to do things like not taking school funding when everyone else is."
The Mississippi contest was the marquee race on a busy June primary day that included New York, Oklahoma, Colorado, Maryland and Utah. In a special House election on Florida's Gulf Coast, voters chose Republican businessman Curt Clawson to replace former Rep. Trey Radel, who resigned in January after pleading guilty to cocaine possession.
In New York's Harlem and upper Manhattan, 84-year-old Democratic Rep. Charles Rangel, a 22-term congressman and the third-most-senior member of the House, held a slight lead over state Sen. Adriano Espaillat, bidding to become the first Dominican-American member of Congress. The race was too close to call early Wednesday with an undetermined number of absentee ballots still to be counted.
Rangel, one of the founders of the Congressional Black Caucus, drew criticism last month when he dismissed the 59-year-old Espaillat as a candidate whose only accomplishment was to be a Dominican in a majority Latino district.
