Yes, but it IS important that the Senate have a majority with an R beside their name......or winning the Presidency will be compromised (and boy, do we need a new Senate majority leader!) But the time to fight about RINOs is in the Primaries.
Ayotte will fight Trump like a Democrat.
I don’t know how much that will help with Trump. Plan on it: the Senate will be a bunch of a-hole obstructionists like they never were with Zero.
Trump will have to do everything through the back door or cellar door.
