Adrian Fenty earned the title of the District’s mayor-elect Tuesday, two months after his stunning 142-precinct sweep in the Democratic primary.

The election mystery wasn’t whether Fenty would win, but by how much. The 35-year-old Ward 4 council member, who launched his campaign on June 1, 2005, and proceeded to overwhelm his rivals with seemingly limitless energy, a reputation for responsiveness and charisma, won a staggering 89 percent of the general election tally, or 95,691 votes, with 95 percent of the precincts reporting.
