Kyrsten Sinema doesn’t really fit in with her fellow Senate Democrats. Don’t even ask her whether she watches the Democratic presidential debates.

“I’m not missing anything. I prefer happiness,” Sinema declares in a 25-minute interview, a rare extended conversation with an outlet not based in Arizona. “Look how happy I am.”…

“They will not get my vote on [nuking the filibuster],” Sinema said in her office, outfitted with shiny leather and translucent chairs and boasting a vivid shade of purple that pops from the walls. “In fact, whether I’m in the majority or the minority I would always vote to reinstate the protections for the minority. … It is the right thing for the country.”…

And observers watching her on the Senate floor during a vote would be forgiven for thinking she’s a Republican, considering her chats with GOP senators like Majority Whip John Thune of South Dakota, Tom Cotton of Arkansas and Kevin Cramer of North Dakota.
