President Obama leads Mitt Romney 51 percent to 46 percent in the latest Cincinnati Enquirer/Ohio Newspaper Organization survey, within the poll's margin of error. 

Thirty-six percent of Ohioans think they're worse off than they were four years ago, compared to 23 percent who think they're better off. Yet Obama also has a five-point edge on who would do the best job improving the economy. 

Polling in Ohio over time shows Obama with a narrow but consistent lead -- which is why Romney is on a bus tour of the state this week.
