Ryan, the Tea Party poster boy, testified to Romney’s credentials while Rice acknowledged the nation’s weariness from the two long wars in Iraq and Afghanistan that Bush started but said, “If we are not inspired to lead again, one of two things will happen — no one will lead and that will foster chaos — or others who do not share our values will fill the vacuum. … We do not have a choice. We cannot be reluctant to lead — and one cannot lead from behind.” (Mario B. Cabrera/Rick Recard/Vision Fotos)
