The May 17th primary may be just over a week away, but recent polls have continued to show the Republican race is still a toss-up. At least 40 percent of GOP voters reportedly are still undecided. Respondents say they are most focused on frontrunners Dr. Mehmet Oz and Dave McCormick, though results also show good growth for Kathy Barnette, Jeff Bartos and Carla Sands. They are each gaining some ground in their campaigns.
