This is a very interesting profile of Tulsi Gabbard from the NYer from Nov.2017.
What Does Tulsi Gabbard Believe? Tell me if you can't read it behind the pay wall, and I can copy it. It's long, but interesting. Gets into some of why her politics were initially very conservative. She grew up in a cult...there's no other way to spin that. Some of her "anti-gay" views have "evolved." But, as she comes off as a somewhat "confusing" Democrat to many of us, it is clear that it's hard to gain National office in the very blue state of Hawaii as anything other than a Democrat. How much is she a "free-thinker" and how much is she an ambitious opportunist? Even some of her constituents find her an enigma.
