During the 2016 Philippine presidential election, Castriciones served as PDP–Laban's vice-president for Luzon who also supported the candidacy of then-mayor of Davao City, Rodrigo Duterte, as president of the Mayor Rodrigo R.

In October 2021, he stepped down as secretary to run for senator in 2022 under PDP–Laban. He was also named as the guest candidate under the senatorial slate of Isko Moreno, as he has expressed support to his candidacy for president. Castriciones lost after placing 49th in the official results and garnering over 719 thousand votes.
