LOGAN SQUARE — Ald. Carlos Ramirez-Rosa held onto his 35th Ward seat Tuesday.

With 100 percent of the precincts reporting Tuesday night, Ramirez-Rosa held 59.57 percent of the vote to challenger Amanda Yu Dieterich’s 40.43 percent.

In 2015, Ramirez-Rosa handily beat machine-backed 35th Ward Ald. Rey Colon. Ramirez-Rosa came in with 67 percent of the vote to Colon’s 33 percent, making him the only challenger to knock off an incumbent alderman outright last election.

At 26 years old, Ramirez-Rosa was one of the youngest aldermen to ever be elected to Chicago’s City Council. He was also the first openly gay Latino to be elected to the Council.

Ramirez-Rosa went on to become one of the council’s loudest progressive voices and a vocal critic of Mayor Rahm Emanuel, slamming him for everything from his comments on immigration to the city budget.

The alderman also made headlines for his two separate attempts to run for higher office. Daniel Biss, former gubernatorial candidate, asked Ramirez-Rosa to be his running mate but abruptly dropped him six days later, saying he clashed with the 35th Ward alderman over his support for an effort to isolate Israel and force a settlement with the Palestinians.

And when U.S. Rep. Luis Gutierrez announced his retirement, Ramirez-Rosa was one of many to throw his hat into the ring for Gutierrez’s spot. The 35th Ward alderman ultimately dropped out of the race and backed Jesus “Chuy” Garcia instead.

This election cycle, Ramirez-Rosa held challenger Yu Dieterich up as his opposite, criticizing the first-time candidate for her donations from developers, including one from controversial landlord Mark Fishman.

Toward the end of the campaign, Yu Dieterich, a branding professional with ties to local schools, started a website dedicated to slamming Ramirez-Rosa, and he started one to combat the attacks.

The 35th Ward includes parts of Logan Square, Avondale, Hermosa, Irving Park, and Albany Park.
