The Arizona senator believes she single-handedly saved the U.S. Senate.

What does the future hold for Kyrsten Sinema? The Arizona senator, who’s best described as a dull person’s idea of an interesting person, famously flounced from the Democratic Party last December. While she’s remained a part of the Democratic caucus since then, she’s now seeking reelection outside of its auspices and against a more institution-minded member of her former party, in the form of Representative Ruben Gallego—who’s not been subtle about his antipathy for the incumbent. So for the first time in a long while, Sinema’s been forced to consider the possibility that her time in Washington may be coming to an end.

But if remarks attributed to her in a new book by McKay Coppins are any guide, she seems sanguine about her future and determined to go out with her trademark delusions of grandeur. As Insider reported this week, Sinema makes a cameo in Coppins’s Romney: A Reckoning, in which she’s totally not mad about her dim reelection prospects. “I don’t care. I can go on any board I want to. I can be a college president. I can do anything,” she apparently told Mitt Romney. “I saved the Senate filibuster by myself. I saved the Senate by myself. That’s good enough for me.” She is, sadly, correct about her chances of cashing out. But the idea that she “saved the Senate” raises a rather obvious question: “From what, though—and for who?”
