His running mate, Marion Andres, was elected to his first term as vice mayor under Teodoro after defeating two other candidates.

[2][3][4] During the passage of Typhoon Ulysses in November 2020, the Marikina River surpassed the water levels brought by Tropical Storm Ondoy in 2009, resulting in flooding throughout the city.

[5] Later that year, Teodoro submitted a complaint to the Department of Environment and Natural Resources against BFCT, a construction firm owned by the family of Bayani Fernando.

Teodoro claimed that the flooding caused by the passage of Typhoon Ulysses was a result of the construction firm's land reclamation project along the Marikina river.

Fernando denied Teodoro's claims, commenting that the flooding was the result of the narrowing of the river and the construction of the Manalo Bridge.

[6] The department would ultimately approve Teodoro's request to remove the reclaimed land, culminating in his ouster from the Nationalist People's Coalition.

It sought to improve the public healthcare infrastructure, conduct a safe return to in-person classes, and to continue the welfare programs enacted by his administration.

[12] Marion Andres, his running mate, expressed his plans of establishing a "physical health center", if reelected.

[14] In an interview with OneNewsPH, Fernando expressed regret in endorsing Teodoro in earlier races, calling it a mistake.

[21] The alliance between the two soured following the onslaught of Typhoon Ulysses, with media outlets such as The Manila Times describing the race as a "bitter rivalry".

Team BF, the main opposition coalition slated Tumana Barangay Captain Ziffred Ancheta to run against Andres.

The first district covers the barangays of Barangka, Calumpang, Industrial Valley Complex, Jesus de la Peña, Malanday, San Roque, Santa Elena, Santo Niño and Tañong.

[54] Fernando's party, the Nationalist People's Coalition nominated former vice mayor Jose Fabian Cadiz in his place.

On the other hand, the United Nationalist Alliance under Team MarCy nominated the first lady of Marikina, Marjorie Ann Teodoro to challenge Cadiz for the seat.

Like her husband in the mayoral race, Teodoro defeated Cadiz in a wide margin, winning in all nine barangays within the district.

Quimbo handily defeated de Guzman in his bid to reenter the House of Representatives, winning in all seven barangays within the district.
