RENO, Nev. - Returning to Nevada for the second day in a row today, Mitt Romney declared that the four debates that concluded Tuesday have "diminished" the president's campaign.

"You know they have really propelled our campaign," Romney said. "We're seeing that across the country. People are coming together. At the same time, I think, in some respects, they've diminished the president's campaign.

"Under President Obama you really don't have a jobs plan. I mean, think of this: We've had four debates and he hasn't been able to describe what his plan is to get this economy going," said Romney. "He hasn't been able to defend it to the American people. I know he's got a lot of discussion. He's trying to talk to people about it but, you know, you can boil what he's saying down to four simple words, and that is: more of the same. And we don't want more of the same.

"He doesn't have a plan to get jobs for Americans. I do, and that's why I'm gonna win," Romney told the crowd of 2,500, which erupted in cheers.

An ABC News/Washington Post poll found this week that Romney has a slight edge over Obama, 49-48, among likely voters.

Today, the Republican candidate tailored his stump speech to specific generations of the American family. Directing the first portion of his remarks to senior citizens, he argued his promise to repeal "Obamacare" would benefit those on Medicare. Romney then turned to people in their forties who are struggling for work. Next, he cited an example of a young woman who had just graduated from college and was struggling to pay off her own college debt.

"This election is a defining election," he said. "It's a defining election not just about big things that are being spoken about in political circles but in the most important things that happen in the American home.

"This election is about your family and families across this country, and the choice we make will have an enormous impact on your family," he said. "I mean, I went through those circumstances, describing seniors and people in their forties and fifties looking for a better job, and kids coming out of college that can't find work, and young kids where you're worried about their future.

"How many here identify with stories like that in your own home?" he asked. "This is an election about your family and the families of America. And I understand what it's going to take to get this country strong again and to provide the answers that your families need."
