Ohio looks up for grabs as GOP primary nears

CINCINNATI (AP) - In swing-state Ohio, support has been swinging in a lot of directions as the Republican presidential primary approaches.

Polls have shown lead changes every month since last fall, and a new statewide poll indicates that about half of likely primary voters still may change their minds by March 6. The Quinnipiac (KWIHN'-uh-pee-ak) University poll released Wednesday found Rick Santorum surging past Mitt Romney, last month's poll leader. Before that, it was Newt Gingrich, before him Herman Cain, and before them, Romney in a tight race over Rick Perry.

The stakes are high in Ohio. The state offers 66 delegates, second only to Georgia in the 10-state Super Tuesday voting. And Ohio's crucial history for Republicans - none has won the White House without carrying Ohio - make it a key test.
