Among Ohio voters, Senator Hillary Rodham Clinton has opened a lead in a hypothetical, head-to-head matchup against former New York Mayor Rudy Giuliani.
A new Quinnipiac University poll has Democrat Clinton ahead of Republican Giuliani 47 percent to 40 percent. The same candidates were tied in a similar survey last month.
Clinton also is out in front when paired with either Senator John McCain or another Republican, former Senator Fred Thompson.
And, the poll finds Clinton maintains a strong lead over Senator Barack Obama in the Democratic primary race. She has 44 percent to his 15 percent.
The pollsters questioned more than 1,400 Ohio voters.
