Walker is a flawed candidate who has been hammered endlessly by negative ads targeting him as a chronic liar, a violent husband and father. His opponent is a preacher with his own domestic baggage but Dems never care about that from their own. Kemp had a strong ground game so maybe he can help Walker get over the line or at least into a run off.
Expect some number of holier than thou values voters to not vote for Walker while voting for Kemp.
