Sheffield's dominant victory in mayor's race spanned geography, race and income

Detroit Mayor-elect Mary Sheffield showed up to cast her ballot on Tuesday wearing a T-shirt with a slogan: "Mary for Everybody."

Tuesday night's election returns backed up that credo, as Sheffield won a decisive 77% of the vote, including large margins across geography and different sectors of the city's population.

The victory was amplified further at the precinct level, where she won 98.6%, or 424 of the city's 430 precincts. The outgoing City Council president, who was endorsed by Mayor Mike Duggan, won those precincts by an average of 50 percentage points.
