“Giddy” is not a word people use to describe Jon Tester. The towering senior U.S. senator from Montana is blunt and pragmatic. In the halls of Congress, he’s one of the last surviving rural Democrats. When he’s not in Washington, D.C., Tester runs a dirt farm in Montana that’s been in his family for three generations.

A dirt-farming rural Democrat knows better than to overhype. So it came as a surprise when, one day this winter, Tester showed up visibly excited at the office of his friend Michael Bennet, one of Colorado’s two Democratic senators, to share a tantalizing piece of information.

“I think we’re gonna get this voting-rights thing done,” he said to Bennet.

“You got to be kidding me,” Bennet said.
