Democrat Mary Jo Kilroy snatched a seat from House Republicans on Sunday in a tight Ohio race after elections officials tallied provisional ballots. Kilroy's victory by a little more than 2,000 votes over Republican Steve Stivers put the 15th Congressional District into Democratic hands after the retirement from Congress of Republican Deborah Pryce. County officials released unofficial results Sunday that showed Kilroy with a margin of victory of 2,311 votes out of roughly 300,000 cast, enough to avoid an automatic recount. Provisional ballots are issued at polls to people who believe they were wrongly denied the right to vote. Kilroy was down by 594 votes when officials began counting about 9,600 provisional ballots in her district.
