The Ohio Senate race continues to be a wide open contest, according to a recent Quinnipiac University survey.

Lt. Gov. Lee Fisher (D) led former Rep. Rob Portman (R) in the poll, 42 percent to 31 percent. However, 26 percent of survey respondents were undecided. Secretary of State Jennifer Brunner (D) led Portman by a similar margin, 40 percent to 32 percent.

The poll also continued to show that the majority of voters are undecided in the Democratic primary. The poll showed Fisher and Brunner in a statistical dead heat, with Fisher at 20 percent and Brunner at 16 percent. But 59 percent of voters said they were undecided.

The poll questioned 1,079 Buckeye State voters from April 28 to May 4 and had a margin of error of 5 points.
