"I will not be complicit or silent. I've decided that I would be better able to represent the people of Arizona and to better serve my country and my conscience by freeing myself of the political consideration that consumed far too much bandwidth and would cause me to compromise far too many principles. To that end, I'm announcing today that my service in the Senate will conclude at the end of my term in early January 2019. It is clear at this moment that a traditional conservative, who believes in limited government and free markets, who is devoted to free trade, who is pro-immigration, has a narrower and narrower path to nomination in the Republican Party, the party that has so long defined itself by its belief in those things. It is also clear to me for the moment that we have given in or given up on the core principles in favor of a more viscerally satisfying anger and resentment. To be clear, the anger and resentment that the people feel at the royal mess that we've created are justified. But anger and resentment are not a governing philosophy. There is an undeniable potency to a populist appeal by mischaracterizing or misunderstanding our problems and giving in to the impulse to scapegoat and belittle — the impulse to scapegoat and belittle threatens to turn us into a fearful, backward-looking people. In the case of the Republican Party, those things also threaten to turn us into a fearful, backward-looking minority party."
