I wonder, just speculation mind you, if some libertarians are becoming birthers because the opponent is the socially conservative Cruz. I wonder if they might find another argument if the opponent was the socially conservative Palin, Pence, Santorum, or Jindal.
I doubt if they are actually real birthers. I think that they may just be birthers of convenience.
Just speculation, mind you.
That is not the first idea that comes to my mind but if I cared about this I would search past posts from 2010 and 2011 of those Cruz birthers for comments looking to see if dissed the birthers back then.
I ridiculed the 2011 birthers back then with glee, esp Trump's chumps, so I can only find this amusing.
