WASHINGTON (AP) - It's a narrow win -- but still a win -- for Mitt Romney in Ohio.
    
Romney has 38 percent of the vote to Rick Santorum's 37 percent, with 99 percent of precincts reporting. That's about a 12,000-vote victory for candidate who spent almost four times as much money as his rival in the state.
    
A victory in Ohio is considered pivotal. No Republican has won the presidency without carrying the state in the general election.
    
Ohio Republicans were sharply divided. Interviews with voters as they left polling places show people with incomes under $100,000 supported Santorum, while those with six-figure incomes went for Romney.
    
Working women supported Romney, and women who don't work voted for Santorum.
