ORLANDO, Fla. (AP) - State Rep. Sandy Adams has clinched a narrow victory in her Republican primary and now will try to unseat Democratic U.S. Rep. Suzanne Kosmas.

The results of the five-way primary in the 24th District had been in doubt until Wednesday night when the second-place finisher, former Winter Park City Commissioner Karen Diebel, endorsed Adams.

The state lawmaker from Orlando defeated Diebel by 560 votes, or 0.85 percentage point. Diebel could have challenged the results, but the difference was short of the 0.5 percent required for an automatic recount.

Republicans have made Kosmas of New Smyrna Beach one of their top targets nationally. She took the seat away from the GOP two years ago.
