Which one will beat the Democrat in the fall?
The most competent one. Hovde is more or less following Ron Johnson's spectacularly successful playbook. TT is, I think, a step or two - or three - slow. Fitzgerald has been quiet so far; wonder if he's decided he can't match Hovde's spending. Neumann would have been a US Senator already had he been a tough campaigner; repeated campaigns and rumored campaigns have lead to Neumann fatigue.
Ideologically, between Fitzgerald and Hovde, Fitzgerald has proven he's trustworthy with a strong public record, while Hovde does not have a record; it's up to the voter to decide if he's trustworthy.
Any one should defeat Baldwin. She’s left of Stalin.
I think any of them can beat the Dem.
