You are exactly right.
Some swamp creatures seize upon an excellent ideological position that they then use as a shield to cover the actual aims & effects of their actions. Massie is one such denizen. He parrots the language than many principled people want to hear and they are so roused by hearing their own position they fail to notice they are being conned by someone who hold them & Americans in contempt, takes them for fools.
If anything, he sounds like he's been more transparent than anyone else in Washington.
