We need leadership. We don't need a doubling down on the failed politics of the past.

Behind every small business, there's a story worth knowing. All the corner shops in our towns and cities, the restaurants, cleaners, gyms, hair salons, hardware stores - these didn't come out of nowhere.

Millions of young Americans have graduated from college during the Obama presidency, ready to use their gifts and get moving in life. Half of them can't find the work they studied for, or any work at all. So here's the question: Without a change in leadership, why would the next four years be any different from the last four years?

What matters to me is that I do what I think is right and I see, I'm a numbers guy, that's my attitude. I know we have a debt tsunami coming, we are bankrupting this country and I'm in a position where I can actually advance ideas to prevent that from happening. That's exactly what I should be doing.

College graduates should not have to live out their 20s in their childhood bedrooms, staring up at fading Obama posters and wondering when they can move out and get going with life.

Free enterprise empowers entrepreneurs who have ideas and imagination, investors who take risks, and workers who hone their skills and offer their labor.

The perfection of our union, especially our commitment to equality of opportunity, has been a story of constant striving to live up to our Founding principles. This is what Abraham Lincoln meant when he said, 'In giving freedom to the slave, we assure freedom to the free - honorable alike in what we give, and what we preserve.'

What we heard today was not fiscal leadership from our Commander-in-Chief, what we heard today was a political broadside from our Campaigner-in-Chief.

And if small businesspeople say they made it on their own, all they are saying is that nobody else worked seven days a week in their place. Nobody showed up in their place to open the door at five in the morning. Nobody did their thinking, and worrying, and sweating for them.

President Obama clearly cannot run on his record. All he's offering is more of the same. That's not good. Look at the economy. It's stagnating. And so, what they're now going to try and do is bring this campaign down to little things, distractions, distortions, smear, fear, anger, frustration.

The secret to understanding me is, I'm not trying to be anybody other than who I actually am. People want candid, refreshing leadership. And I've always tried to go with solutions. You know, I've always tried to say, here's how we get our economy growing, here's why we get our debt under control. That's what Mitt Romney is offering.

Our founders got it right when they wrote in the Declaration of Independence that our rights come from nature and nature's God, not from government.

Conventional wisdom on government's role in inequality often has it backwards. Tax reforms have resulted in a more progressive federal income tax; government transfer payments have become less progressive.

I saw Donald Trump give a spirited voice to those of us who don't like the status quo, and I see emerging in front of us the potential for what a unified Republican government can get you, which can be the solutions.

Hope and change? We're not doing that anymore. They're doing attack and blame. And so, I just think people are going to see through this. They want real leadership. They want us to get this country on the right track.
