Sen. Bernie Sanders (I-Vt.) picked up the endorsement of the American Postal Workers Union on Thursday, a group that boasts 200,000 members across the country.
Why it matters: The union promised to lend its organizing power to Sanders' campaign, with the endorsement coming only a few days before the Iowa caucus on Feb. 3. The group also backed Sanders in 2016, per AP.
"But when we judge candidates by their long-term and consistent actions, Bernie Sanders stands out as a true champion of postal workers and all workers throughout the country."— APWU President Mark Dimondstein
