Many Republicans talk about putting America first, but House Speaker Kevin McCarthy (R-Calif.) actually did it on Saturday. He reached across the aisle for Democratic support and steered a short-term budget to passage. Yes, the deal came at the “11th hour,” and it’s far from perfect, but it’s in line with what Mr. McCarthy and President Biden agreed to in May when they avoided a debt ceiling crisis. What occurred this weekend was a victory for governance and political stability over far-right GOP extremists who represent just 2 percent of the U.S. population and were making ever-changing demands, including to slash most domestic programs and build more wall along the southern border. Nearly everyone expected a shutdown. Instead, Mr. McCarthy moved toward the center. He deserves a cheer.
