WASHINGTON >> Resurgent Republicans won control of the House and cut deeply into the Democrats’ majority in the Senate in momentous midterm elections shadowed by recession, ushering in a new era of divided government certain to complicate the final two years of President Barack Obama’s term.

House Speaker-in-waiting John Boehner, voice breaking with emotion, declared shortly before midnight Tuesday that the results were “a repudiation of Washington, a repudiation of big government and a repudiation of politicians who refuse to listen to the people.”

Obama monitored returns at the White House, then telephoned Boehner with congratulations in a call that underscored the power shift.

Incomplete returns showed the GOP picked up at least 58 House seats — the biggest party turnover in more than 70 years — and led for seven more, far in excess of what was needed for a majority. Among the losers was Rep. Tom Perriello, a first-termer from Virginia for whom Obama campaigned just before the election.

On a night of triumph, Republicans also gained at least six Senate seats, and tea party favorites Rand Paul in Kentucky, Mike Lee in Utah and Marco Rubio in Florida were among their winners. But Christine O’Donnell lost badly in Delaware, for a seat that Republican strategists once calculated would be theirs with ease. And they lost the nation’s most closely watched race, in Nevada, where Majority Leader Harry Reid won an especially costly and brutal campaign in a year filled with them.

The GOP also wrested 10 governorships from the Democrats, Ohio and Pennsylvania among them, and gave two back, California and Hawaii.

In New York, Andrew Cuomo won the office his father, Mario, held for three terms. And in California, Edmund G. Brown Jr., was successful in his bid for a comeback to the governor’s office he occupied for two terms more than a quarter-century ago.

The biggest win by far was the House, a victory made all the more remarkable given the drubbing Republicans absorbed at the hands of Democrats in the past two elections. Their comeback was aided by independents, who backed GOP candidates for the first time since 2004, by a margin of 55 percent to 39 percent. Women backed Democrats 49-48, after favoring them by a dozen points in recent elections.

The takeaways came in bunches — five Democratic-held seats each in Pennsylvania and Ohio and three in Florida and Virginia. Incumbents sent to defeat included two committee chairmen, Ike Skelton in Missouri and John Spratt in South Carolina, as well as Paul Kanjorski of Pennsylvania, in Congress more than a quarter-century.

Democrats conceded nothing while they still had a chance. “Let’s go out there and continue to fight,” Speaker Nancy Pelosi exhorted supporters in remarks before television cameras while the polls were still open in much of the country.

But not long after she spoke, Democratic incumbents in both houses began falling, and her own four-year tenure as the first female speaker in history was doomed. She gave no indication of her own plans.

The White House said Obama had called Senate Republican Leader Mitch McConnell and top Democrats as well as Boehner, and pledged to try and find common ground on the issues facing the country. Efforts to revitalize the economy top the list, and Republicans also campaigned calling for spending cuts to reduce deficits, extension of expiring tax cuts for all and repeal of Obama’s cherished health care bill — all areas ripe for confrontation in the months ahead.

For her part, Pelosi issued a statement saying, “We must all strive to find common ground to support the middle class, create jobs, reduce the deficit and move our nation forward.”

With unemployment at 9.6 percent nationally, interviews with voters revealed an extraordinarily sour electorate, stressed financially and poorly disposed toward the president, the political parties and the federal government.

Sen.-elect Paul, appearing Tuesday night before supporters in Bowling Green, Ky., declared, “We’ve come to take our government back.”

About four in 10 voters said they were worse off financially than two years ago, according to exit polls and pre-election surveys. More than one in three said their votes were an expression of opposition to Obama. More than half expressed negative views about both political parties. Roughly 40 percent of voters considered themselves supporters of the conservative tea party movement. Less than half said they wanted the government to do more to solve problems.

Republicans were certain of at least six Senate pickups, including the seat in Illinois that Obama resigned to become president. Rep. Mark Kirk won there, defeating Alexi Giannoulias.

Democratic Sens. Russell Feingold in Wisconsin and Blanche Lincoln in Arkansas were turned out of office. In addition, Republicans scored big in races for Democratic seats without incumbents on the ballot. Former Rep. Pat Toomey won a close race in Pennsylvania, North Dakota Gov. John Hoeven won easily there, and former Sen. Dan Coats breezed in a comeback attempt for the Indiana seat he voluntarily gave up a dozen years ago.

Democrats averted deeper losses when Gov. Joe Manchin won in West Virginia — after pointedly distancing himself from Obama — for the unexpired portion of the late Sen. Robert C. Byrd’s term, and Attorney General Richard Blumenthal was victorious in Connecticut, dispatching Linda McMahon, former CEO of World Wrestling Entertainment. Sen. Barbara Boxer was elected to a fourth term in California, overcoming a challenge from Carly Fiorina.

The GOP gubernatorial gains came after a campaign in which their party organization spent more than $100 million, nearly double what Democrats had.

Among the incumbents who fell were Ted Strickland in Ohio, defeated by former Rep. John Kasich, and Chet Culver in Iowa, loser to former Gov. Terry Branstad.

In California, former Gov. Edmund G. Brown Jr. was elected to the office he held for two terms more than a quarter-century ago.

In a footnote to the brutal politics of the campaign, Republican-turned- independent Lincoln Chafee was elected governor of Rhode Island. Obama campaigned in the state in the campaign’s final week. But he declined to endorse the Democratic candidate, Frank Caprio, out of what the White House said was respect for Chafee, who had endorsed the president in his own presidential race two years ago.

A Republican takeover of the House would usher in a new era of divided government after two years in which Obama and fellow Democrats pushed through an economic stimulus bill, a landmark health care measure and legislation to rein in Wall Street after the near collapse of the economy in 2008.

Paul’s triumph in Kentucky completed an improbable rise for an eye surgeon making his first race. He drew opposition from the Republican Party establishment when he first launched his bid, then struggled to adjust to a statewide race with Attorney General Jack Conway.

Rubio, also running with tea party support, won with 49 percent of the vote in a three-way race in Florida, months after he forced Gov. Charlie Crist to leave the Republican Party and run as an independent. Democratic Rep. Kendrick Meek ran third.

But a third tea party-backed candidate, O’Donnell, who went from a virtual unknown to primary winner to fodder for late-night comedians in the span of a few months, lost overwhelmingly to Democrat Chris Coons in Delaware. Republicans had counted on taking the seat from the Democrats early this year, but that was before O’Donnell defeated veteran Rep. Mike Castle in a September primary. Democrat John Carney easily won the seat that was Castle’s for nearly two decades.

Not all the Republican newcomers were party crashers.

In New Hampshire, Republican Kelly Ayotte won a Senate seat, defeating Democratic Rep. Paul Hodes. Former Bush administration official Rob Portman won a seat in Ohio, and Rep. Jerry Moran won in Kansas and Rep. Roy Blunt in Missouri.

Democratic Sen. Patrick Leahy of Vermont was re-elected to his seventh term and Barbara Mikulski her fifth. New York Sens. Charles Schumer and Kirsten Gillibrand also won, as did Sen. Ron Wyden in Oregon and Boxer in California In Hawaii, Democratic Sen. Daniel Inouye was elected for a ninth time to the seat he has held since 1962.

Republican Sen. Jim DeMint, who won a second term in South Carolina, has been working to establish a nationwide standing among conservatives. He was instrumental in supporting tea party challengers in several primaries this spring and summer at a time the GOP establishment was backing other candidates.

In Alabama, Sen. Richard Shelby was re-elected easily, as were Republican Sens. Tom Coburn in Oklahoma, Richard Burr in North Carolina, John Thune in South Dakota, Johnny Isakson in Georgia, David Vitter in Louisiana, John McCain in Arizona, Chuck Grassley in Iowa and Mike Crapo in Idaho.
