Democrat Tim Kennedy won a special election Tuesday to finish off the term started by fellow Democrat Brian Higgins in a Buffalo-area congressional seat.
The Associated Press called the race soon after Kennedy had a 75 percent to 25 percent lead over Republican West Seneca supervisor Gary Dickson in early results.
His victory brings the number of Democrats in the House to 213. There are 217 Republicans and five vacancies.
The district has been safe for Democrats since Higgins narrowly won his first term in 2004. Kennedy will need to run for a full, two-year term in November.
