Pat Toomey in Pennsylvania took away a fifth Democratic Senate seat for Republicans. But the GOP needed to win all five uncalled races to take control of the Senate. Toomey beat Democratic Rep. Joe Sestak

WASHINGTON (AP) — Republicans grabbed Senate seats from Democrats in Wisconsin, Arkansas, North Dakota and Indiana on Tuesday, but a Democrat's win in West Virginia may preserve his party's Senate majority.
Veteran Democratic Sens. Russ Feingold of Wisconsin and Blanche Lincoln of Arkansas lost their re-election bids. But West Virginia Gov. Joe Manchin held off millionaire Republican John Raese to keep a Democrat in the seat held for half a century by the late Robert C. Byrd.
To gain the 10 seats they need for a Senate majority, Republicans would have to win all the remaining tight races, and pull off upsets in California and Washington.
Tea party champions won high-profile races in Florida and Kentucky, spearheading a likely cadre of libertarian-leaning Republicans who will press party leaders to be more adamant about lower taxes, less spending and smaller government.
Rand Paul of Kentucky and Marco Rubio of Florida rocked the GOP establishment last spring by routing leadership favorites in party primaries. Then they beat back Democrats' efforts to paint them as too extreme, winning comfortably on Tuesday.
In Utah, tea party-backed Mike Lee won easily after snatching the Republican nomination from Sen. Bob Bennett in March.
"Tonight there's a tea party tidal wave," said an exultant Paul.
Feingold, a three-term Democrat, lost to GOP newcomer Ron Johnson in Wisconsin. Best known for efforts to tighten campaign finance laws, Feingold was the only senator to vote against the so-called Patriot Act passed after the 2001 terrorist attacks, calling it a dangerous infringement on civil liberties.
Johnson, 55, made a fortune in manufacturing plastics. He wants to repeal the nation's new health care law, which he calls the greatest single assault on freedom in his lifetime.
Lincoln fell to GOP Rep. John Boozman in Arkansas, where President Barack Obama lost by 20 percentage points two years ago.
Conservatives said Lincoln, who won her first two Senate elections comfortably, was too close to Obama, while liberals said she wasn't loyal enough.
Indiana voters sent Republican Dan Coats back to the chamber after a 12-year absence. Coats, who spent a decade in the Senate before stepping down in 1998, defeated Democratic Rep. Brad Ellsworth. The seat is being vacated by Democrat Evan Bayh.
In North Dakota, Republican Gov. John Hoeven easily won the Senate seat that retiring Democrat Byron Dorgan held for 18 years.
But Connecticut's attorney general, Richard Blumenthal, kept his state's open Senate seat in Democratic hands, fending off pro wrestling entrepreneur Linda McMahon.
Paul, who beat Democratic state Attorney General Jack Conway, is an ophthalmologist who had not sought office before. His father is Rep. Ron Paul of Texas, a hero to many libertarians. He won the seat vacated by GOP Sen. Jim Bunning.
Rubio, a former Florida House speaker, is not a political newcomer. But he defied his party's establishment nonetheless, refusing to stand aside for Gov. Charlie Crist in the Senate race. Crist ran as a third-party candidate, but Rubio defeated him and Democratic Rep. Kendrick Meek. The Florida seat's previous two occupants were Republicans who stepped down.
Christine O'Donnell, another tea party darling, lost to Democrat Chris Coons in Delaware. She also had won a stunning GOP primary victory, beating longtime Rep. Mike Castle, who was expected to top Coons. But she raised eyebrows with curious comments about witchcraft, the First Amendment and other topics, and failed to extend her popularity to the broader November electorate.
Tea partiers were hoping for up to three more Senate victories in western states. They included Nevada, where Sharron Angle hoped to beat Senate Majority Leader Harry Reid, and Colorado, where Ken Buck took on Democratic Sen. Michael Bennet.
But a tempestuous three-way race in Alaska threatened to let Democrat Scott McAdams win a once-hopeless race for GOP Sen. Lisa Murkowski's seat. Murkowski was running a rare write-in campaign after losing the Republican primary to another tea partier, Joe Miller.
In New Hampshire, Republican Kelly Ayotte kept her party in control of the seat being vacated by Judd Gregg. The former state attorney general defeated Democratic Rep. Paul Hodes.
Rob Portman won the Ohio Senate race, keeping a Republican in the seat that Sen. George Voinovich is vacating. Portman spent 12 years in the U.S. House starting in 1993. He later was budget director and then U.S. trade representative under President George W. Bush. Portman defeated Democratic Lt. Gov. Lee Fisher.
In Kansas, GOP Rep. Jerry Moran won the Senate seat vacated by Republican Sam Brownback, who was elected governor Tuesday.
And Rep. Roy Blunt kept Missouri's open Senate seat in Republican hands.
Easily winning re-election as expected were Sens. Mike Crapo, R-Idaho, David Vitter, R-La., Charles Grassley, R-Iowa, John McCain, R-Ariz., Jim DeMint, R-S.C., Richard Shelby, R-Ala., Tom Coburn, R-Okla., Richard Burr, R-N.C., John Thune, R-S.D., Johnny Isakson, R-Ga., Ron Wyden, D-Ore., Patrick Leahy, D-Vt., Kirsten Gillibrand, D-N.Y., Charles Schumer, D-N.Y., and Barbara Mikulski, D-Md.
A nine-seat Democratic loss would produce a 50-50 tie that Vice President Joe Biden, the Senate's official president, would break in the Democrats' favor.
The race to fill the open Illinois Senate seat once held by Obama pitted Republican Mark Kirk, a five-term House member, against state treasurer Alexi Giannoulias.
In Pennsylvania, Democratic Rep. Joe Sestak beat Republican-turned-Democratic Sen. Arlen Specter in the Senate primary, and he faced GOP nominee Pat Toomey.
Democrats technically hold 57 Senate seats, but two independent senators caucus with the party.
