New York Times: “As Democrats fight for control of Congress, prominent left-wing politicians including Mr. Sanders of Vermont and Ms. Ocasio-Cortez of New York are increasingly inserting themselves into primary races to elevate progressives in competitive battleground districts.”“That’s a departure from the progressive playbook of years past, which generally focused on backing candidates in deep-blue turf where campaigns tended to focus more on liberal ideology and less on electability in general-election contests.”“The effort aims to rebut the conventional wisdom that running moderate Democrats who appeal to centrists and Republicans with middle-of-the-road policies is the best strategy in competitive races. Now, progressives are saying that candidates with policies aimed at helping working families and critiquing the wealthy can win anywhere.”
