The WHOLE LOT of the Republican Party - can chalk up the consequences of yesterdays elections to itself.
Trump included because he has done more to further the polarization and divides that the Democrats have engineered, rather than work for any kind of unity unless it is to himself.
The GOP Leadership has demonstrated it is just part and parcel one with the Democrat leadership, so - if you want Socialism and Statism, why bother with wannabes when you have Pelosi, Schumer and their party masters to choose from?
The GOP may finally get to keep the Whigs company by the end of the next cycle the way they are going.
Which is a good thing.
