With African-Americans voting in large numbers, Republican make sweeping gains in the Washington D.C. municipal elections.
Washington D.C. held municipal elections on this day with black men voting and assisting at polling places for only the second time ever. Republicans won all the city-wide contests and a strong majority on both the Board of Common Council and the Board of Alderman, together with five of seven wards. African-American turnout was estimated at around ninety percent of eligible voters and helped place the city firmly in the hards of largely radical Republicans. (By John Osborne)
