Brunner and Fisher

Looking for clues about how a possible Lee Fisher/Jennifer Brunner primary might play out in Ohio?

When we did an Ohio poll last month we found that 52% of Democrats had a positive opinion of both of them, 18% had no opinion about either of them, 14% had a positive opinion of Fisher but not Brunner, 9% had a positive opinion of Brunner but not Fisher, and 7% had a negative opinion of both of them.

In other words, there doesn't seem to be a clear early favorite.
