Cristóbal Arias Solís (born 10 August 1954) is a Mexican lawyer and politician, belonging to the National Regeneration Movement (Morena). He has been a senator of the Republic three times: from 1988 to 1991, 1994 to 2000, and from 2018 to 2021.[1] He also served as a federal deputy from 1982 to 1985 and from 1991 to 1994. He has been a candidate for governor of Michoacán on three occasions for the Party of the Democratic Revolution and the Fuerza por México alliance. Since 5 July 2021, he is a senator to the Congress of the Union for Michoacán.
He participated as a candidate for governor in the 1992 Michoacán state elections, coming in second place behind the PRI candidate, Eduardo Villaseñor Peña. The PRD denounced fraud on the part of the PRI government[5][6][7] and, in the midst of massive mobilizations, Governor Villaseñor resigned only 21 days after taking office.
Due to the death of the constitutional governor Eduardo Villaseñor, the electoral process was brought forward to the 1995 Michoacán state elections. Cristóbal Arias Solís was re-elected to represent the PRD for the government's candidacy after internal difficulties with the pre-candidate Roberto Robles Garnica who alleged fraud and challenged the process.[8][9][10]
In 2001 he supported the candidacy of PRD candidate Lázaro Cárdenas Batel who would become governor. Under the argument that the PRD was no longer an instrument for transformation and social justice, and also ceased to be the opposition, he resigned from the party in a letter dated April 2016.[13]
In March 2018, he became a candidate for senator for the Juntos Haremos Historia alliance headed by Morena, a party founded by Andrés Manuel López Obrador.[14][15] In the 2018 federal elections in Michoacán, he was elected as a second-formula senator.[1]
In the 64th Congress, he chaired the Government Commission of the Senate of the Republic, structurally the most important in the Upper House.[16]
