I haven't seen any discussion on this in a while, so I wanted to started a new thread about the top legislative chamber targets for each party in 2020. I didn't find a whole lot on Google other than
this Cook article, which lists D targets (tossup or lean) as:
-AZ Sen, AZ House
-FL Sen
-IA House
-MI House
-MN Senate
-NC Senate
-PA Senate, PA House
-TX House
It lists top R targets as:
-AK House (from a coalition)
-ME Senate
-MN House
-NH House, NH Senate
Agreements/disagreements? The author notes that he came close rating the North Carolina House and the Wisconsin Senate as competitive.
