The Emurua Dikirr Constituency parliamentary by-election is a hotly contested race, pitting President William Ruto's UDA party against former Deputy President Rigathi Gachagua's DCP party.

• The by-election was triggered by the death of the former Member of Parliament, Johana Ng’eno, in a helicopter crash on February 28, 2026.
• Key issues dominating the campaigns include poor road networks, inadequate healthcare, lack of clean water, and poor infrastructure.
• The race features five candidates, with David Kipsang Keter (UDA) and Vincent Rotich (DCP) seen as the frontrunners in this battle for influence in the Rift Valley region.

Following his ousting as Deputy President in October 2024, Rigathi Gachagua is employing strategies reminiscent of former ODM leader Raila Odinga.

• Key strategy involves solidifying regional support.
• Central figure is Rigathi Gachagua, former Deputy President.
• Gachagua is consistently shaping the national discourse post-impeachment.

A High Court hearing challenging the impeachment of former Deputy President Rigathi Gachagua was marked by laughter and sharp exchanges as Dr. Daniel Gikonyo, cardiologist at Karen Hospital, testified that Gachagua was genuinely ill and not evading the Senate.

• Dr. Gikonyo stated he treated Gachagua for severe chest pain on October 17, 2024.
• Lawyers for the Senate and Deputy President Prof. Kithure Kindiki questioned the authenticity and timing of Gachagua's hospital records.
• The hearing also revealed Dr. Gikonyo had briefed President William Ruto on Gachagua's health after obtaining his consent.
