City Councilmember Janeese Lewis-George, who identifies as a Democratic socialist, is leading the race for mayor of Washington, D.C., according to recent polling data.

Lewis-George holds a double-digit advantage over former City Council Member at-Large Kenyan McDuffie, a Democrat, in the contest to become the nation's capital's next mayor. Lewis-George has served on the D.C. City Council for six years.

The polling results indicate significant voter support for Lewis-George's candidacy as the city prepares to select its next chief executive. McDuffie previously served as an at-large member of the City Council before launching his mayoral campaign.

The race will determine who succeeds the current mayor in leading the district government of Washington, D.C., which serves as both a city and the seat of the federal government.
