Sharline Nabulime beat Sean Durkee to win a rainy Ward 6 special election  on Tuesday.

She earned 384 votes (or 56% of the vote) while Durkee earned 299.

Nabulime, who is originally from Uganda, becomes the first African-American to win a city council seat in Waltham. She works as a home health care aide.

As a first-time candidate, she ran a professional campaign, doing all the work required to win.

Nabulime was spotted around 9:00 a.m. on election day at one of the polling stations. Throughout the day, her volunteers stood in the rain holding signs at strategic locations.

Roughly 21% of Ward 6’s 3,300 voters cast ballots Tuesday.

The seat became vacant after longtime councilor Bob Waddick stepped down earlier this year to seek the city clerk’s job.
