I think she will run against Kathy Hochul.
Do we even know if Hochul's district will still be around? Or have legislators decided to erase Slaughter's district instead?
I haven't heard too much lately but I believe that the current plan is to keep a district for Hochul and try to make her district safer by giving her the Niagara County parts that Slaughter had. What I guess the general consensus is that there will be an upstate Republican eliminated along with a downstate democrat. The most likely republican to get the ax would be Burkle (she deserves it... honestly one of the dumbest people I have ever met... and I'm not saying that because I disagree with her policies... It's because I've met her and had to deal with her). I don't know how Turner's victory has changed the redistricting plans.
So... in answer to your question... I am fairly confident that Hochul will have a district in 2012 and probably one that is more favorable to her. I don't know exactly what areas it would cover but my best guess is parts of Erie county. If it doesn't include any of Monroe county I don't see a reason why Brooks would move to run against her in a district that doesn't include any of her base. If the district ends up including Monroe county it looks like Brooks would be a decent candidate for the GOP to put up against Hochul.
