TAMPA, Fla. (AP) - Mitt Romney launched his fall campaign for the White House with a rousing, remarkably personal speech to the Republican National convention and a prime-time TV audience Thursday night, proclaiming that America needs "jobs, lots of jobs" and promising to create 12 million of them in perilous economic times.
"Now is the time to restore the promise of America," Romney declared to a nation struggling with 8.3 percent unemployment and the slowest economic recovery in decades.
Often viewed as a distant politician, he made a press-the-flesh entrance into the hall, walking slowly down one of the convention aisles and shaking hands with dozens of delegates. The hall erupted in cheers when he reached the stage and he waved to his shouting, chanting supporters before beginning to speak.
"I accept your nomination for president," he said, to a roar of approval. Then he pivoted into personal details of family life, recounting his youth as a Mormon, the son of parents devoted to one another, and a married man with five rambunctious sons.
He choked up at least twice, including when he recalled how he and wife Ann would awake to find "a pile of kids asleep in our room."
Romney aimed numerous jabs at President Barack Obama, his Democratic quarry in a close and uncertain race for the White House, and drew cheers when he vowed to repeal Obama's signature health care law.
"This president can tell us it was someone else's fault. This president can tell us that the next four years he'll get it right. But this president cannot tell us that you are better off today than when he took office," Romney declared.
Clint Eastwood, legendary Hollywood tough guy, put the case for ousting Obama plainly moments before Romney made his entrance. "When somebody does not do the job, you've got to let 'em go," he said to the cheers of thousands in the packed convention hall.
Obama, Vice President Joe Biden and the Democrats counter with their own convention beginning next Tuesday in Charlotte, N.C.
His own speech over, Romney was joined by running mate Paul Ryan, then their wives, and finally a stage full of their children and grandchildren. Confetti and thousands of red, white and blue balloons floated down from the rafters. They joined popular gospel singer BeBe Winans on "America the Beautiful."
Beyond the heartfelt personal testimonials and political hoopla, the evening marked one of a very few opportunities any presidential challenger is granted to appeal to millions of voters in a single night.
The two-month campaign to come includes other big moments - principally a series of one-on-one debates with Democrat Obama - in a race for the White House that has been close for months. In excess of $500 million has been spent on campaign television commercials so far, almost all of it in the battleground states of Florida, North Carolina, Virginia, New Hampshire, Ohio, Iowa, Colorado and Nevada.
Romney holds a fundraising advantage over Obama, and his high command hopes to expand the electoral map soon if post-convention polls in Pennsylvania, Michigan, Wisconsin and perhaps elsewhere indicate it's worth the investment.
Romney was often almost gentle in his criticism of Obama.
"I wish President Obama had succeeded because I want America to succeed," he said. "But his promises gave way to disappointment and division."
"This isn't something we have to accept," he said, appealing to millions of voters who say they are disappointed in the president yet haven't yet decided to cast their votes for his Republican challenger.
"Now is the moment when we can stand up and say, 'I'm an American. I make my destiny. And we deserve better! My children deserve better! My family deserves better! My country deserves better!"
Romney's remarks came on a night when other speakers filled out a week-long portrait of the GOP nominee as a man of family and faith, savior of the 2002 Winter Olympics, savvy and successful in business, yet careful with a buck. A portion of the convention stage was rebuilt overnight so he would appear surrounded by delegates rather than speaking from a distance, an attempt to soften his image as a sometimes-stiff and distant candidate.
"He shoveled snow and raked leaves for the elderly. He took down tables and swept floors at church dinners," said Grant Bennett, describing Romney's volunteer work as an unpaid lay clergy leader in the Mormon church.
Following him to the podium, Ted and Pat Oparowski tenderly recalled how Romney befriended their 14-year-old son David as he was dying of cancer. "We will be ever grateful to Mitt for his love and concern," she said simply.
Shouts of "USA, USA" echoed in the convention hall as several Olympic medal winners came on stage, a reminder of Romney stepping in to help rescue the faltering 2002 Olympic Games in Salt Lake City.
As for Obama, Romney said, "Many Americans have given up on this president, but they haven't ever thought about giving up. Not on themselves, Not on each other. And not on America."
Romney did not mention the wars in Iraq and Afghanistan and made only the most fleeting references to social issues. He said, "As president, I will protect the sanctity of life. I will honor the institution of marriage. And I will guarantee America's first liberty: the freedom of religion."
The economy is issue No. 1 in the race for the White House, and Romney presented his credentials as the man better equipped than the president to help create jobs. Speaker after speaker testified to the help their received from Bain Capital, the private equity firm that he created - and that Democrats argue often took over companies, loaded them down with debt and then walked away with huge fees as bankruptcy approached.
"When I told him about Staples, he really got excited at the idea of saving a few cents on paper clips," businessman Tom Stemberg said of the office supply store chain he founded with backing from Bain.
Romney' offered no new information on what has so far been a short-on-details pledge to reduce federal deficits and create 12 million jobs in a country where unemployment stands at 8.3 percent.
Still, he said, "Let me make this very clear, unlike President Obama, I will not raise taxes on the middle class" - a rejoinder to one of the Democrats' most frequent accusation
Romney would have to nearly double the current, anemic pace of job growth to achieve 12 million jobs over four years. That's conceivable in a healthy economy. Moody's Analytics, a financial research operation, expects nearly that many jobs to return in four years no matter who occupies the White House, absent further economic setbacks.
Romney's steps for achieving the employment growth include deficit cuts that he has not spelled out and a march toward energy independence that past presidents have promised but never delivered.
He has called for extension of tax cuts due to expire at all income levels at the end of the year, and an additional 20 percent across the board cut in rates. But he has yet to sketch which tax breaks he will eliminate or cut to prevent deficits from rising.
Nor has he been forthcoming about where to make the trillions in spending cuts needed to redeem his pledge of major deficit reduction, or about his promise to rein in Medicare or other government benefit programs before they go broke.
Ryan, the chairman of the House Budget Committee, has called for remaking Medicare into a program in which the government would send seniors checks to be used to purchase health care insurance.
Under the current approach, beneficiaries pay premiums to the government, which then pays a part of all of their medical bills, and Democrats say the GOP alternative would expose seniors to ever-rising out-of-pocket costs.
Obama's surrogates missed no opportunity to criticize Romney, the convention proceedings or Ryan's own acceptance speech.
"He lied about Medicare. He lied about the Recovery Act," Obama's campaign manager, Jim Messina, emailed Democratic donors in a plea for cash.
"He lied about the deficit and debt. He even dishonestly attacked Barack Obama for the closing of a GM plant in his hometown of Janesville, Wisconsin - a plant that closed in December 2008 under George W. Bush."
The evening sealed a triumph more than five years in the making for Romney. He ran unsuccessfully for the nomination in 2008 after a single term as a moderate Republican governor of a liberal Democratic state.
This year, as then, he was assailed as a convert to conservatism, and a questionable one at that, as Gingrich, former Pennsylvania Sen. Rick Santorum and other rivals battled him for the nomination. With a superior organization and an outside group that spent millions criticizing his foes, Romney eventually emerged as the nominee in early spring.
