Marcos Sierra latest to run for council

And then there were six?

Just days after Columbia University professor Abigail Martin jumped into the city council race, she appears to be joined by yet another challenger: Marcos Sierra.

Although he hasn’t seemed to officially file candidacy paperwork yet, the male district leader for Assemblywoman Nathalia Fernandez’s district made his announcement on Twitter Tuesday he was jumping into the fray.

“It is my excited and humble pleasure to announce my candidacy for the 11th Council District,” Sierra said on social media. “The political landscape in the Bronx is evolving, and it’s time to truly have proportional representation in the 11th Council District.”

Sierra joins a race that already includes real estate attorney Dan Padernacht, educator Eric Dinowitz — son of Assemblyman Jeffrey Dinowitz — museum docent Dionel Then, climate activist Jessica Haller, and Martin.

Andrew Cohen, the current councilman, was formally nominated to the Bronx supreme court by the Bronx Democratic County Committee, meaning he will have to vacate his seat before his term ends in 2021.

Cohen has said he doesn’t plan on officially leaving his post until the end of the year, meaning there could be a special election for his seat sometime in March.

Sierra is a former member of Community Board 7, and at least as of February, was an assistant program director for Rain senior care, according to published reports.

And Sierra does have one thing in common with another one of the candidates seeking to succeed Cohen: He was once an intern at a newspaper, the Norwood News.

Dionel Then also interned at The Riverdale Press in 2017.

Voters are expected to elect Cohen and two civil court judges to the supreme court during the Nov. 3 general election.
