As this Senate election is concurrently held with a presidential election, some presidential candidates have presented
senatorial slates, which typically have up to 12 names to round up the twelve seats up for election. Due to a
dispute,
PDP–Laban, the ruling party, was split into two factions that are part of different coalitions. Some candidates are included in multiple coalitions as guest candidates.
1Sambayan After releasing its choices of presidential and vice presidential candidates on June 12, 2021,
Independence Day, Howard Calleja, one of the convenors of the opposition group
1Sambayan (Isambayan) said that former
Bayan Muna representative
Neri Colmenares was one of the group's choices to have their endorsement. After the announcement of
Leni Robredo's initial 11-person slate, 1Sambayan said it would also announce who they would support soon, while maintaining that they supported unconditionally the Robredo–
Francis Pangilinan ticket for president and vice president.
Antonio Trillanes accused Makabayan candidate Neri Colmenares of supporting
Isko Moreno instead of backing 1Sambayan's candidate Leni Robredo. Makabayan denied endorsing the incumbent Manila Mayor Isko Moreno, pointing out they had yet to make a decision on the matter. On January 19, 2022, 1Sambayan endorsed 7 Senate bets in Robredo's ticket. Later that month, they endorsed Neri Colmenares, who is not included in Robredo's slate.
Aksyon Demokratiko Aksyon Demokratiko was in talks with
Nationalist People's Coalition,
United Nationalist Alliance, and
Partido para sa Demokratikong Reporma for an alliance. There have also been discussions between Aksyon president
Isko Moreno and PDP–Laban's
Manny Pacquiao faction, as well as between Moreno and the
Liberal's
Leni Robredo. On September 27, 2021, Aksyon announced two candidates,
Samira Gutoc, who ran and lost in 2019 with the Liberals, and
Carl Balita, for election. Former vice president and senator
Noli de Castro filed to run for senator with Aksyon, but withdrew less than a week later.
Jopet Sison, of
Ipaglaban Mo! fame, replaced him. On February 24, Aksyon Demokratiko adopted
John Castriciones of the
PDP–Laban Cusi wing as a guest candidate, after a Duterte volunteer group he led endorsed Moreno the week before.
Labor and Ecology Advocates for Democracy Leody de Guzman of
Partido Lakas ng Masa (PLM) unveiled a Senate slate composed of nine people including two incumbents. The three people running under De Guzman's party PLM are labor leader
Luke Espiritu of
Bukluran ng Manggagawang Pilipino (BMP) and environmentalists Roy Cabonegro and David D'angelo. On October, de Guzman endorsed six more names as guest candidates. On February 18,
Teddy Baguilat was revealed as the 12th and final candidate included in the PLM's slate. After the completion of the slate, it was branded as "Labor and Ecology Advocates for Democracy."
Lacson–Sotto slate Senate President
Tito Sotto announced his and
Panfilo Lacson's candidacies for vice president and president, respectively, in July 2021. They also presented their initial list of possible senatorial candidates; these include mostly incumbents and former senators. In July 2021, an alliance between the
Nationalist People's Coalition (NPC),
United Nationalist Alliance (UNA) and
Partido para sa Demokratikong Reporma has been the works with the possibility of the inclusion of
Aksyon Demokratiko. On October 14, Lacson hinted at a "surprise" senatorial candidate on their camp, while having already revealed 10 names, that includes incumbents. A day later, Lacson presented a 14-person slate (two more than the 12 open seats), which includes three from Lacson's Reporma, and six from Sotto's NPC. At the start of the campaign period, the campaign dropped
Herbert Bautista from their slate, citing Bautista's desire to represent the NPC in the
UniTeam slate of Marcos and Duterte. In order to remain on multiple slates, the guest or common candidates agreed not to publicly endorse a particular presidential and vice presidential candidate. The next day, the campaign dropped
Win Gatchalian from their slate, citing his personal endorsement of the Marcos-Duterte tandem at the UniTeam proclamation rally. Other common candidates, such as
Migz Zubiri, who also attended the UniTeam event, and
Dick Gordon, who attended the Robredo-Pangilinan rally, were not dropped because no public endorsements were made. On early April, Zubiri was ultimately dropped when he endorsed Marcos on a rally in his home province of
Bukidnon.
MP3 Alliance PDP–Laban acting president
Manny Pacquiao has been in separate talks with
Aksyon Demokratiko's
Isko Moreno and the Liberal Party's
Leni Robredo. On October 15, Pacquiao presented his senatorial slate that included candidates running for reelection, progressive leaders, and former senators. Pacquiao by that time only had eight candidates on his slate, as he said there were other people who wanted to be
guest candidates.
Team Robredo–Pangilinan The
Liberal Party was in talks of alliance-building with
Panfilo Lacson,
Joel Villanueva,
Nancy Binay, and
Isko Moreno. Minority Leader and Liberal Vice-chairman Franklin Drilon stated that if Vice President
Leni Robredo chose not to run for the presidency, the party would be open to coalesce under
Manny Pacquiao. In August 2021, the party released the names of its initial slate for the Senate consisting of three incumbents, one former senator, and one former candidate. In September 2021, Robredo met separately with Moreno and Pacquiao. On October 15, Robredo announced an 11-person slate, which included former rivals such as Vice President
Jejomar Binay, and
Francis Escudero, whom she beat for vice president in 2016. The 12th slot was being negotiated between
Makabayan's
Neri Colmenares and labor leader Sonny Matula. Colmenares said that it's Robredo's prerogative as the presidential candidate to choose her Senate slate. Colmenares later said that it was former senator Antonio Trillanes who was behind his exclusion from the line-up. Robredo announced that Sonny Matula was the 12th person in her Senate slate on October 22. The slate was branded "Team Robredo–Pangilinan" or TRoPa during Robredo's proclamation rally in
Naga, Camarines Sur.
Tuloy ang Pagbabago Coalition The Tuloy ang Pagbabago coalition's slate is mostly composed of current members of the Cabinet, former senators seeking a return to the Senate, or personalities identified with President
Rodrigo Duterte. During the national convention by the
Alfonso Cusi faction, the party nominated mostly Cabinet members and allied lower House representatives in its initial slate. The coalition will hold a proclamation rally and present their 11-point agenda in March.
UniTeam Partido Federal ng Pilipinas, one of the constituent parties of the
UniTeam, announced that former presidential spokesperson
Harry Roque of the
People's Reform Party is a member of their senatorial slate. On January 20, 2022, UniTeam released their 10-person Senate slate. On February 5, the alliance added former Information and Communications Technology secretary
Gregorio Honasan as the eleventh person on their slate; this is after Honasan's Reform Party nominated former Senator
Bongbong Marcos and
Sara Duterte for president and vice president, respectively. Sara Duterte announced
Robin Padilla as the 12th and last member on February 16; however, the Marcos camp later stated that he was not part of their official slate. By March 11, Duterte said that Padilla is a guest candidate. == Candidates ==
