TAMPA, Fla.– 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.
