Top Republicans meeting for the first time since U.S. Election Day say the party failed to unseat President Barack Obama because nominee Mitt Romney did not respond to criticism strongly enough or outline a specific agenda with a broad appeal.

In conversations at the Republican Governors Association meeting in Las Vegas, a half dozen party leaders predicted the Republican Party will lose again if it keeps running the same playbook based on platitudes in place of detailed policies. Instead, leaders asserted, the party needs to learn lessons from its loss, respect voters' savvy and put forward an agenda that appeals beyond the white, male voters who are its base.

Little more than a week after Romney came up short in his presidential bid, the party elders were looking at his errors and peering ahead to 2016's race. Some of the contenders eying a White House run of their own were on hand and quietly considering their chances. New Jersey Gov. Chris Christie scheduled a private meeting on the sidelines with Haley Barbour, the former Mississippi governor who is widely seen as one of the Republican Party's sharpest political operatives.

"We need to have a brutal, brutally honest assessment of everything we did," Barbour said. "We need to take everything apart ... and determine what we did that worked and what we did that didn't work."

Louisiana Gov. Bobby Jindal said in an interview that the party needs to acknowledge the defeat.

"We clearly got beat and we need to recognize that," Jindal said.

His comment came after he criticized Romney over a remark the former presidential hopeful made to donors. In a call Wednesday, Romney cast his loss in a different light, asserting that Obama won re-election because of the "gifts" the president had already provided to blacks, Hispanics and young voters and because of the president's effort to paint Romney as anti-immigrant.

Jindal told reporters that Romney's comments, initially reported by the New York Times and the L.A. Times, were "absolutely wrong."

“We have got to stop dividing the American voters,” Jindal said. “If we’re going to continue to be a competitive party and win elections on the national stage, and continue to fight for our conservative principles, we need two messages to get out loudly and clearly. One, we are fighting for 100 per cent of the votes. And second, our policies benefit every American who wants to pursue the American dream, period.”

Wisconsin Gov. Scott Walker also weighed in, CNN reported, saying the Republican Party is not just for people "who are currently not dependent on the government."

The criticism continued Thursday, with several Republicans including Iowa Gov. Terry Branstead, criticizing Romney's remarks to donors. Branstead told Politico that he didn't think Romney's comments were helpful, saying he thinks Republicans should "focus on the future and not make excuses for the past."

Other potential White House contenders such as Jindal, Virginia Gov. Bob McDonnell and Wisconsin Gov. Scott Walker were outlining a vision for the party in coming elections.

"We need to figure out what we did right and what we did wrong, how we can improve our tone, our message, our technology, our turnout — all the things that are required to win elections," McDonnell said. "We are disappointed, but we are not discouraged."

With polls in hand and shifting demographic trends in mind, these Republicans are looking at how best to position the party to make inroads with growing numbers of Hispanic, black and young voters who overwhelmingly voted Democratic last week. The Republicans were still smarting over constant criticism of Romney from Obama and Vice President Joe Biden — and what they saw as Romney's often ineffective response.

"They spent all their time making Mitt Romney unacceptable and making him out to be someone who was untrustworthy and unacceptable to enough of the American people — and it worked," Branstad said in an interview.

In the hallways at the conference, the governors and their top advisers uniformly blamed Romney's loss on an uneven communications strategy. They said Romney allowed himself to be branded a corporate raider who put the interests of the wealthy above those of middle-income voters.

"We didn't have effective means by which to counter the attacks the Obama-Biden campaign took against Mitt Romney and his team," Walker said. "I just don't think you can let that go unanswered."

Republicans point to attacks, lack of specifics

Time and again, the governors pointed to Obama attacks that settled into voters' minds.

"His whole campaign was a fear-and-smear attack to make Romney unacceptable and to blame George Bush for anything that happened while Obama was president," Barbour said. "This was all personal: that Romney is a vulture capitalist who doesn't care about people like you, ships jobs overseas, is a quintessential plutocrat and is married to a known equestrian."

Barbour added: "An attack unanswered is an attack admitted to."

Had the criticism been shown to be false or unfair, the results might have been better, said Bill Bennett, an education secretary in the Reagan administration and an informal adviser to governors.

"We were in a big fight. We came with a knife; they came with a gun," Bennett said. "If Mitt Romney had responded and had we responded on his behalf — and had his campaign pushed back more forcefully — I think it would have been a different result."

Jindal, however, attributed Romney's loss to a lack of "a specific vision that connected with the American people."

"His campaign was largely about his biography and his experience," Jindal said. "But time and time again, biography and experience is not enough to win an election. You have to have a vision, you have to connect your policies to the aspirations of the American people. I don't think the campaign did that and as a result, this became a contest between personalities and — you know what? — Chicago won that."

"The president's campaign, if you will, focused on giving targeted groups a big gift," Romney said, citing immigration proposals aimed at Hispanics and free contraception coverage that appealed to young women. "He made a big effort on small things."

White House press secretary Jay Carney disputed Romney's assessment, telling reporters travelling with Obama to New York City on Thursday that policies allowing more young people to go to college or stay on their parents' health plans are good for the country and the economy.

"I think that view of the American people or the electorate and the election is at odds with the truth of what happened last week," Carney said.

Romney said his campaign, in contrast, had been about "big issues for the whole country." He said he faced problems as a candidate because he was "getting beat up" by the Obama campaign. He said the debates allowed him to come back.

The Republican nominee didn't acknowledge any major missteps and said his team had run a superb campaign.
