WASHINGTON (AP) — Washington, D.C., on Tuesday will hold a districtwide primary for federal and local offices that will be unlike any election the nation’s capital has previously held.The primary takes place against a uniquely complex backdrop. Residents are contending with an unprecedented level of ongoing federal intervention by President Donald Trump in how the district looks and functions. A rare combination of open seats in top offices has caused a ripple effect down the ballot. And local election officials are rolling out a new ranked choice voting system.The competitive Democratic primary field for mayor includes Ward 4 Councilwoman Janeese Lewis George, former At-Large Councilman Kenyan McDuffie and five others. Their key endorsements suggest the fault lines that have formed between the party’s establishment and its more progressive wing.

Lewis George has endorsements from four of her fellow council members, including at-large member Robert White, who is running for U.S. delegate to Congress. She also has the backing of several progressive organizations including the Working Families Party, the Metro D.C. Democratic Socialists of America and Our Revolution, a political committee affiliated with allies of independent Vermont Sen. Bernie Sanders, who caucuses with Democrats.
