"We're going to have to invest in infrastructure to make sure that we're competitive. And I've got a plan to do that. We're going to have to invest in science and technology. We've got to vastly improve our education system. We have to look at energy and the potential for creating green jobs that can not just save on our energy costs but, more importantly, can create jobs in building windmills that will produce manufacturing jobs here in Ohio, can put rural communities back on their feet by working on alternative fuels, making buildings more energy efficient. We can hire young people who are out of work and put them to work in the trade."

-- Barack Obama, Ohio Democratic presidential primary debate
