The area is also suitable for dairy farming. A majority of the people are small-scale farmers. Other economic activities include informal sector activities such as small and micro-enterprises, largely trading. A few people are in salaried employment, mainly teaching, civil service and private sector enterprise. The economic activities of the people of Kitutu Chache have always demanded the availability of efficient means of transportation and communication.

Kitutu Chache happens to be the mythical origin of all the Abagusii clans and clannism therefore has not played quite an important role in determining election winners. Lawrence Sagini was the first Member of Parliament from Kisii District and held the office of Member of Parliament from independence for one term. He was also the first African Minster of Education under the first African government. At the Limuru KANU conference of l966, it had been suggested that he be the Nyanza VP among the group of 8 vice presidents in charge of the provinces in a ploy hatched by Tom Mboya to neutralize Oginga Odinga's vice presidency.

Sagini spent most of his political life in the cold until during a brief absence and temporary absence of Onyonka saw him nominated for the office at the grassroots level. By the time of Onyonka’s death, Sagini was too old to regain momentum to reenter politics and had moved to his retirement settlement scheme home in Borabu constituency. Sagini passed away on 3th August 1995.

The first decade of independence saw a pitched battle for supremacy between then MPs Lawrence Sagini (Kitutu) and James Nyamweya ((Nyaribari). The two were perennially antagonistic and, when Joseph Murumbi stepped down as VP, there was talk that Sagini threatened to lead a revolt if Nyamweya was appointed to replace him. Later, Sagini was ousted by Dr Zachary Onyonka in 1969, who had just returned from the US with a PhD in Economics and Planning. The rivalry between the Nyaribari people and the Kitutu clan took a new turn with the rising influence of Nyaribari’s Mr Simeon Nyachae. Nyachae’s influence grew when he was appointed Chief Secretary. He was particularly at odds with Onyonka, who claimed that Nyachae required all Kisii MPs wishing to visit the President to seek clearance from him (Nyachae). In the 1985 grassroots elections, a group perceived to be pro-Nyachae routed out Onyonka and his entire team in polls that saw Sagini elected. This set the stage for a lengthy rivalry between Nyachae and Onyonka. The rivalry was exacerbated by the latter’s incarceration at Kodiaga Prison after a man, Uhuru Ndege, was killed during a violent campaign incident.

When Onyonka realized that Nyachae had trained his eyes on politics, he rallied several MPs, namely David Onyancha, Omanga and Chris Obure into his camp. MPs Abuya Abuya, Atebe Marita and Reuben Oyondi remained neutral. A series of rallies were held across Kisii starting with the one at Kebirigo market to popularize what was then named the 4-Os camp — Obure, Onyancha, Omanga and Onyonka. Onyonka led the 4-Os in declaring that Kisii MPs were united behind President Moi and were opposed to what they termed "a wealthy man who was out to unseat popular leaders" in the impending1988 election. They came up with what they termed the ‘Kebirigo Declaration’ in which those loyal to the President resolved to handle their issues directly with the Head of State without referring to any mediator. They also resolved that no political interference would be tolerated in other people’s constituencies. Their campaign seemed to have borne fruit when Onyonka went unopposed in the 1988 elections that saw him govern until his passing away in 1996.

Kitutu Chache is one of the constituencies in the three districts of Gusiiland which have always produced high-voltage political showdowns in the run-up to elections every five years.The constituency also holds the record of having had one man representing it in Parliament for an uninterrupted period of twenty-five years. That was the late Dr Zachary Theodore Onyonka.

The vacancy of Zachary Onyonka saw the disappearance of Nicholas Siro who had been a fierce challenger of Zachary and the emergence of Jimmy Angwenyi who captured the seat in a early 1997 by election and the two subsequent elections of 1997 and 2002 until the 2007 general election when he lost to Richard Momoima Onyonka who had battled him for more than 13 years to retake his father’s old job.
