BEDFORD HEIGHTS, Ohio – With early voting starting next week in the battleground state of Ohio, both presidential candidates courted voters there Wednesday with greater urgency, using a sport legend and China trade to make their cases.

Mitt Romney showcased his celebrity support, including golfing legend Jack Nicklaus. President Barack Obama campaigned on a college campus in northwest Ohio.

Romney, 65, is ramping up his schedule as he tries to tamp down complaints from some Republican leaders that he has spent too much time raising money. With two new polls showing Obama leading in Ohio, Romney stepped up his attacks on the incumbent during his two-day bus tour of the state, which started Tuesday and included three events Wednesday.
