According to the new Mitt Romney biography, Sinema thinks she single-handedly saved the Senate and can now retreat to a cushy post-Congress life.

Kyrsten Sinema doesn't care one bit if she wins re-election, according to a new book.

"I can go on any board I want to. I can be a college president. I can do anything," she said.

Sinema told Romney said she saved the filibuster and the Senate and that's "good enough for me."
