By a shocking 18-vote margin, the Republican controlled Senate voted to terminate President Trump’s arguably unconstitutional, but probably legal, national emergency. It was a bold and surprising stand by some unusual suspects, such as Sen. Marco Rubio, R-Fla., and a confirmation from others, like Sen. Mitt Romney, R-Utah, that their promises to protect the Constitution are more than empty words.

Then there’s Sen. Ben Sasse, R-Neb. Sasse has spent the better part of the last three years pontificating to anyone who’ll listen to him about the unique threat Trump poses to the office of the presidency.

“I don’t have any desire to beat the president up, but it’s pretty clear that this White House is a reality show, soap opera presidency,” said Sasse in September, an assessment that isn’t incorrect, but one so obvious it’s almost redundant. He regularly teases leaving the Republican Party, and wrote an entire book essentially impugning the core of Trumpism. He takes to the Senate floor to rail against Trump’s rhetorical attacks on the Justice Department and has repeatedly stoked rumors that he plans on primarying the president in 2020.
