Our dear libertarian "base" felt that we weren't pulling America over to our side fast enough so they just let go of the rope and walked away, knowing America would lurch left. And they have the nerve to blame those of us who stayed in the fight....
The thing of it is, they are so far to the right they've come up on the left. Before this election that was a lesson only the voters of a few states had learned...now it's pretty clear for everyone.
These days, in that picture the libertarians would have hold of the middle of the rope and be pulling it towards the trees (with the small band of Republicans that still give a damn about their own party's founding principles). Get a clue about what we stand for. I suggest starting with John Locke.
