Well, this is awkward. I've been proven a Cassandra of sorts. In mitigation of such hubris I can only say that many other, much better, minds pointed all this out before me...but, you will notice, not any liberal ones. Anyway,
http://www.thedailybeast.com/articles/2015/03/25/everything-the-white-house-told-you-about-bowe-bergdahl-was-wrong.html Let's dust it up, then. It's evident the US traded a wartime traitor for five high-value enemy combatants. The administration knew, or reasonably should have known, of these circumstances before illegally approving the exchange for political purposes. See,

So, what now? You're likely thinking, "Great, everyone is a dick - what should I do about it?" I'm working on that. I implore you to do the same. For example, does this meet constitutional boundaries for impeachment and/or removal? I say yes.
