Video: US election: Mitt Romey tries to woo Ohio on Republican campaign trial Mitt Romney attempted to renew his presidential campaign in the battleground state of Ohio with an appeal to entrepreneurs. The Republican portrayed himself as the candidate who would support small business. We are free in this nation pursue happiness as we choose, and now and then, there is a person out there that has some idea and goes out an pursues it, not because the government told them to do it, but because this idea came into their mind and they said I am going to go out there and try this idea. Most of the ideas don't work. It is the nature of starting something up, but now and then, they really do, and when they do, they lift other people who get to work there. And, if they are successful beyond their dreams, many, many people get great jobs and a bright future. That is how our economy works," he said. Mr Romney, appearing at an airport with his running mate Paul Ryan, also criticised Mr Obama for his positions on issues including taxes, health care and foreign policy. "With the developments in the Middle East these days, when we have an ambassador assassinated, when we have 20 thousand people killed in Syria, when we have a Muslim Brotherhood leader become the new president of Egypt, when we have Iran moving closer and closer to a nuclear weapon, we don't have a president calling these things bumps in the road, we have a president who takes this serious and gets America on track to shape world affairs," he said. Mr Romney hopes to reset his campaign starting with the bus tour in the battleground state, where Mr Obama holds a 51 to 46 per cent lead, according to a poll by Ohio newspapers released on Saturday.
