We've all known for years that the GOP establishment was a collection of spineless grifters, gutless cowards, back-stabbing traitors, pathetic wimps in gimp suits who give up any and all principles when told to do so by the DNC masters.
Now, we've gotten some good ones in office over the past few election cycles, but Mitch McConnell is still in control. And that means that there are a majority of RINOs and traitors in the GOP to keep him in power.
Any spine McConnell showed over the last four years was loaned to him by Trump. And when Trump left, so did that spine.
