President Ruto seeks a second term, focusing on a strategic running mate choice to broaden his coalition.
Efforts to woo Wiper leader Kalonzo Musyoka aim to secure votes from the Eastern region, with over 1.4 million voters.
Musyoka rejects the offer, while speculation suggests the current Deputy President Kindiki may be dropped.
Ruto may consider candidates from Western, Nyanza, or Coast regions to gain support and campaign financing.
