Kyrsten Sinema and Mark Kelly have boldly gone where few Arizonans from their party have gone before. Their joint membership in the âWorldâs Most Exclusive Clubâ marks the first time since 1953 that the Grand Canyon State has been represented in the Senate by a pair of Democrats. Senator Sinemaâs unconventional fashion choices began a âbuzzâ upon her arrival, but she followed a conventional political path to the Upper Chamber. Thatâs not the case for her new Arizona colleague. Like John Glenn and Jack Schmitt before him, Mark Kellyâs path to the Senate was âout of this world:â to stay there, Historyâs third astronaut-turned-senator must continue to defy political gravity.
