As we explained this morning, the liberal intelligentsia is losing its collective mind over a letter penned by 47 GOP senators. In it, they remind Iran - as well as our rogue President - that the U.S. Constitution exists, separation of powers exists, and that Obama's effort to grant Iran a pathway to a nuclear arsenal doesn't hold much water if Congress isn't on board. In short, they explain the workings of the United States government in language that even Democrats (or a rogue terrorist state) can understand.
