Right now Strange has the upper hand as 1. the Incumbent and 2. a well known state level office holder.
Moore will pull in a small but loyal percentage of the state, but his well has been poisoned with a lot of people and that may be too much for him to overcome.
Brooks is a wildcard -- he is a U.S. Congressman but outside of his northern Alabama district he is not a well known quantity statewide. So he will be fighting a name recognition battle against Strange and Moore.
The rest of the R field is not well known, and no matter how much chest pounding might be done, the D candidates have no chance what-so-ever.
Right now I say it is Strange's race to lose, Moore will make noise but I don't see him overcoming the stigma of twice being removed from the state court, and Brooks will be fighting a recognition battle in the southern part of the state.
There will undoubtedly be a runoff... Strange has money, because he's an establishment guy ($2.6m just from the Senate reelection PAC).
So who makes the GOP runoff? Guessing Roy Moore will as he plays the persecuted crusader angle. He is already 70 years old, but I don't believe that will be a hindrance.
The second runoff slot could be a dogfight between Mo and Strange. Mo's been gaining on name recognition, but he will have some trouble in South Alabama.
I want Strange gone... if it comes down to Moore and Strange, the media will destroy Moore. If it's Brooks vs. Moore, then they will destroy the entire state. That would be fun.
