Here's some of what Paul Ryan will say in his speech tonight

Via USA Today:

"I accept the calling of my generation to give our children the America that was given to us, with opportunity for the young and security for the old -- and I know that we are ready," Ryan will say, according to excerpts released by the campaign. "Our nominee is sure ready. His whole life has prepared him for this moment – to meet serious challenges in a serious way, without excuses and idle words. After four years of getting the run-around, America needs a turnaround, and the man for the job is Governor Mitt Romney." ...

"The present administration has made its choices. And Mitt Romney and I have made ours: Before the math and the momentum overwhelm us all, we are going to solve this nation's economic problems," Ryan will say. "And I'm going to level with you: We don't have that much time. But if we are serious, and smart, and we lead, we can do this."
