Of all the Republicans campaigning in Iowa, perhaps none is campaigning harder than Ben Sasse, a Republican senator from Nebraska. Mr. Sasse isn’t running for president. He’s running against Donald Trump. The particular focus of his opposition deserves a lot more attention.
Mr. Sasse is a notable voice in this debate. He’s a heavyweight conservative—a grass-roots favorite, the furthest thing from the “establishment.” Before winning his Senate seat in 2014, he had never held elected office. He was the president of Midland University in Fremont, Neb., when he decided that he had to try to get to Washington and help restore the constitutional vision of the Founders.
Which is his point in Iowa: “We have a President who does not believe in executive restraint; we do not need another,” said Mr. Sasse in a statement announcing that he would campaign with Marco Rubio, Ted Cruz and other “constitutional candidates.” On Twitter, Mr. Sasse issued a string of serious questions for Mr. Trump, including: “Will you commit to rolling back Exec power & undoing Obama unilateral habit”?
That’s a good question for every Republican candidate. President Obama has set a new lawless standard for Washington that might prove tempting for his successor from another party. Why suffer Democratic filibusters when you can sign an executive order? Why wait two years for legislation when you can make it happen overnight? The temptation to cut constitutional corners would be powerful given the pent-up conservative desire for a Washington overhaul.
