^ A: Towards the 2020 general elections, the party, under the influence of candidate Luis Arce, adopted centre-left strategies, abandoning the party's historical radical strategies. After Arce assumed the presidency of Bolivia, an internal division arose between the so-called "arcistas" (those who respond to the current president) who constitute a more centre-left profile and the "evistas" (attached to the former president) who are closer to the radical left. Some time later the Arcista faction took the party's presidency and became the main faction of the party.

Movement for Socialism – Political Instrument for the Sovereignty of the Peoples (Spanish: Movimiento al Socialismo – Instrumento Político por la Soberanía de los Pueblos; MAS or MAS-IPSP), is a socialist political party in Bolivia. Its followers are known as Masistas. In the December 2005 election, MAS-IPSP won the first ever majority victory by a single Bolivian party. The party continued to rule until 10 November 2019, and was victorious again in the 2020 elections.

MAS-IPSP evolved out of the movement to defend the interests of coca growers. Evo Morales has articulated the goals of his party and popular organizations as the need to achieve plurinational unity, and to develop a new hydrocarbon law which guarantees 50% of revenue to Bolivia, although political leaders of MAS-IPSP recently interviewed showed interest in complete nationalization of the fossil fuel industries, as well as the country's lithium deposits.

MAS-IPSP is the dominant force in municipal politics in Bolivia. In the most recent municipal elections in 2015, it was the only party to contest leadership of all 339 municipalities. In all, the mayors of 227 municipalities belong to the party, as do 1,144 of the country's 2,022 municipal council members.

During Arce's government, the party was divided into two internal factions: the "Arcistas" (Renovator Bloc), which defends Luis Arce's management and seeks the renovation of the party leadership, which is chaired by Grover García, and the "Evistas", which defends Evo Morales's leadership and seeks his re-election in the 2025 Bolivian general election. On 4 October 2023, President Luis Arce and Vice President David Choquehuanca were expelled from the party by a decision of the board chaired by Evo Morales. However, the Arcista faction did not recognize the expulsion.

By February 2025, due to MAS prohibiting him from running for president in the 2025 general election, Morales left the party to join the Front for Victory.
