Rasmussen has it in a virtual tie. He thinks the GOP will lose MA and ME but will pick up ND and NE. Then there are three more Democrat leaners and two GOP leaners. That leaves seven seats that are rated toss-ups of which six are Democrat seats going in. IN is the lone GOP seat left at risk. Dems are trying to protect FL, MT, OH, PA, VA and WI. Of these, I have the highest hopes for MT and VA. The rest may depend on turnout.
Randita don’t you have a spredsheet for this?
