Democrat John Mannion will launch a second bid for a state Senate seat in the Syracuse area he narrowly lost last year to Republican Bob Antonacci.

Mannion on Friday announced he would run again for the district, which Antonacci is vacating after he won a state Supreme Court judgeship on Tuesday.

“Last year, I ran for State Senate because our communities deserve to get our fair share of state aid, investment, and focus,” Mannion said.

“We deserve real leadership and a dedicated public servant who will work to strengthen our schools, invest in job training programs, and protect our water and natural resources. As our next State Senator, I will fight for Central New York families and small businesses in Albany.”

Mannion narrowly lost to Antonacci by 2 percentage points in 2018, considered a wave year for Democrats. The party gained control of the state Senate for the first time in a decade last year, picking up key seats on Long Island and in the Hudson Valley.

It’s not year clear when a special election would be called for Antonacci’s seat, which was held previously by Sen. John DeFrancisco, a Republican.

Gov. Andrew Cuomo indicated on Wednesday he could hold it for April 28, the same day as the state’s presidential primary, a day in which Democrats are expected to head to the polls for what’s expected to be a still-competitive nominating contest.
