In 2005, Huayta was appointed deputy mayor of the Avaroa Canton and was later made departmental counselor to the Oruro prefecture from 2006 to 2008, demonstrating his and the neighborhood councils' close relations with the ruling Movement for Socialism.

At the end of his term, Huayta amicably split with the ruling party and founded his own, Alternative Civic Integration, with which he unsuccessfully contested a seat on the Oruro Municipal Council in 2021.

[2] Starting in 1999, Huayta began actively participating in grassroots organizing;[6] he developed an extensive career in associative and communal spaces, especially in the neighborhood councils encompassing the city's peri-urban areas.

His efforts expanded in subsequent years to include other development projects, such as the provision of improved sewerage, added public lighting, and enhanced internet and natural gas access.

Following the 2004 municipal election, Huayta was appointed deputy mayor of his native Avaroa Canton,[11] and when the MAS won control of the Oruro regional government,[12] he was made departmental counselor to the prefecture from 2006 to 2008.

[15] Huayta did not seek a second term chairing Oruro's delegation in 2014,[15] but disagreed with discrepancies in the designation of his successor, Senator Ricardo Aillón – objections that culminated in his estrangement from the ruling party.

Although he stated his intent to operate independently for his tenure's duration, not taking part in party conferences and the like,[18] he simultaneously rejected narratives implying a more concrete break in support for the government:[19] "Until the last ... second that I am a deputy, I will be from the MAS.

"[20] Near the end of 2014, Huayta undertook the task of organizing his own party, Alternative Civic Integration – Socialist Front (INCA-FS), which branded itself as a left-wing second option to the preeminent MAS.

[27] At the same time, it can also be noted that Huayta was actually barred from running, as were most outgoing parliamentarians, owing to a controversial ruling by the Supreme Electoral Tribunal which established that incumbent legislators did not meet the necessary residency requirements to seek local public office.

Within days of assuming office, one councillor declared themself independent, and both allegedly backed the election of MAS legislator Henry Rojas to the presidency of the municipal council, prompting Huayta to denounce them as traitors and demand their resignations.
