Three states are on the clock for control of the U.S. Senate as we have less than three months until the 2020 election.

Arizona, Kansas, and Michigan all went red in the 2016 presidential election. But since, Trump has been in office, the pendulum has swung to the left. In Arizona, Kyrsten Sinema became the first Democrat to win a U.S. Senate seat since 1988 in the 2018 midterm election. During that same election cycle, both Kansas and Michigan flipped their governors’ mansions blue, electing Laura Kelly and Gretchen Whitmer, respectively.
