I wonder what it was that made them leave? The consistently improving unemployment numbers? The steadily rising economy? The the evidence that aggressive anti-US foreign dictatorships are begrudgingly reaquainting themselves with respect, moderation, and diplomacy on the international stage? Could it be the attempts to prevent the US from going down the same failed path the EU is stuck on in regards to immigration? Maybe it was the protecting and defending of the Constitution that pushed them over the edge?
