His career was marked by a willingness to compromise, often aligning with political rivals. This pragmatism, while seen by supporters as prioritizing national interests, also led critics to question the cost of such compromises and the fate of the causes he championed.
Odinga's involvement in significant political events, including the 2007 disputed election and the subsequent power-sharing agreement that made him Prime Minister, highlighted the fragility of Kenya's democratic progress. He also played a prominent role in the 2010 constitutional referendum, which expanded rights and strengthened governance structures.
The Supreme Court's annulment of the 2017 presidential election underscored the role of judicial institutions in checking executive power, though persistent electoral mistrust remained a challenge. Odinga's subsequent "handshake" with President Uhuru Kenyatta led to the Building Bridges Initiative, which aimed to address governance issues but ultimately failed in court.
In the period leading up to his death, Odinga led protests against the government on issues like the cost of living and taxation. However, a new generation of protesters emerged, questioning established political hierarchies and demanding accountability on economic hardship and corruption.
In March 2025, Odinga and President William Ruto signed a framework for cooperation on issues including devolution and electoral reform. This agreement, however, caused divisions within Odinga's party, with some factions accusing Ruto's party of not upholding its commitments.
