Together with
Cheick Oumar Sissoko, in 1996 Mariko founded a political party, African Solidarity for Democracy and Independence (SADI), in opposition to
President Alpha Oumar Konaré. He is the Secretary-General of SADI, which is avowedly
leftist. Mariko was chosen as the party's candidate for the
April 2002 presidential election at its first ordinary congress in March 2002. In the election, he finished in 12th place with .88% of the vote. In the
July 2002 parliamentary election, Mariko was a candidate in
Kolondiéba constituency. At the end of a SADI national conference, on February 24, 2007 Mariko was designated as the party's candidate for the
April 2007 presidential election. In a press conference on May 29, Mariko denounced the electoral commission and the Constitutional Court for their handling of the election, saying that the former should be dissolved. He was also sharply critical of the main opposition coalition, the
Front for Democracy and the Republic, in which he did not participate. He won a seat in the
National Assembly of Mali in the
July 2007 parliamentary election on a SADI list in Kolondiéba; the other candidate on the list was
Moussa Coumbéré. The SADI list took second place, with 21.28% of the vote, in the first round, behind the
National Congress for Democratic Initiative (CNID) list, which received 25.29%. However, the SADI list won in the second round with 61.76% of the district's vote.
2012 military coup d'etat Following the coup d'état that suspended Mali's democratic institutions on the night of 21–22 March 2012, Oumar Mariko and his SADI political party created MP22, the
Mouvement populaire du 22 mars (22 March People's Movement) supporting the coup plotters. In the
July–August 2013 parliamentary election, Mariko was re-elected to the National Assembly. He subsequently stood as a candidate for the post of President of the National Assembly, but in the vote held on 22 January 2014, the governing party's candidate,
Issaka Sidibé, won easily, with 115 votes against 11 for Mariko. ==References==
