Assuming Jim Justice wins in West Virginia, the Senate GOP now only needs to gain one more seat ? or none at all, depending on the presidential race ? to take the majority.
Holding the Senate will be tough for Democrats
It seems like you’re right. OTOH, if the Democrats run challengers who are well-targeted toward the states they run in, there doesn’t seem to be any reason they can’t pick up some states.
What states? Florida? Missouri? Texas? I’m afraid that it will take a blue tsunami; a mere blue wave won’t suffice.
