A net gain is a given barring a big pro rat swing rat funding edge or not.
20 at a minimum I’d guess.
My guess is there will be between 200 and 230 House Republicans elected.
There’s not much good news east of the Hudson. Every seat conservatives expect to pick up is based on speculation.
The eastern NH seat (Shea-Porter) is the only seat where things are “going well enough”.
MA-6, Tierney, north of Boston is interesting
