On Capitol Hill this week, an ideologically mixed group of House Democrats called on their party to embrace a “fighting spirit of patriotic economic populism”.

“Democrats need to wake up and stop defending elites and the establishment,” the representative Chris Deluzio, who represents a competitive Pennsylvania district, said in a floor speech.

“This embrace of economic patriotism might sound and look different depending on where in this country and who the messenger is,” he continued. “But we agree that the era of a spineless Democratic party must end.”
