This isn't about Harry Reid. This is about destroying traitors. McConnell is a traitor. If he thought having a Democrat replace him was such a bad thing, he shouldn't have decided to be a traitor.
Remember what McConnell paid for in Mississippi. He tarnished the entire Tea Party nation wide with those false accusations.
If the GOP takes the Senate and McConnell wins, then McConnell will be majority leader. If the Dems win, then Reid will run the Senate.
Now, in which one of those senarios will Ted Cruz and Jeff Sessions get to be committee chairmen?
