Are you sure? Pressler twice endorsed Obama.
The odds now are 70-30 that Republicans will take the Senate, the RATS would have nothing to offer Pressler to caucus with them.
I wouldn’t doubt that Manchin will switch parties too.
Another RAT senator has said he may switch too if R’s take the Senate, but I forget the name/state, Angus King- Maine?
Hairy Reed is toast. We will net no less than 7 seats.
