Toward the end of my time working for Cruz, the Senate voted against repealing Obamacare. John McCain, terminally ill with brain cancer, dramatically cast a late-night vote, giving the bill a thumbs-down on the Senate floor. Cruz, a proponent of repealing Obamacare, was livid. I had long admired McCain, and found his action an inspiring example of an American patriot putting his country before his party.
