Nasa leaders have ganged up against Opposition Chief Raila Odinga to “teach him a political lesson” in what promises to be a nasty and gruelling political duel.Bungoma Senator Moses Wetang’ula has now declared that he will not take back the Senate Minority leadership position and for the first time blamed Raila for being behind his ouster.Living true to his vow that the NASA divorce would be “nasty and messy”, Wetang’ula has promised a relentless war on Raila and his ODM party. “We will continue giving them in small measures and calculated dosage to ensure they enjoy no comfort,” vowed Wetang’ula, narrating his woes during the closed-door NASA Parliamentary Group meeting on Thursday.“I was subjected to name-calling, harassment and humiliation in the presence of my brother Raila Odinga and when he stood up to speak, he said nothing about what had happened. His silence showed a distinct message that my ouster was rehearsed and purely his deal,” he said.But the new battle, especially for the soul of the Luhya nation, the second largest community in Kenya, is likely to produce three centres of power and radically shift the political landscape. Wetang’ula and ANC Party leader Musalia Mudavadi have launched a campaign against Raila in Western Kenya in a calculated tribal arithmetic. Dubbed “Project Luhya Nation”, the two leaders have vowed to field a single presidential candidate in 2022 and hinted at folding ANC and Ford Kenya into a single formidable political entity. Wiper Leader Kalonzo Musyoka, who is now pushing for the registration of NASA as a political party, is seen as gravitating towards the Musalia, Wetang’ula axis. Then there is Deputy President William Ruto, who is assembling his 2022 political arsenal, backed by a massive financial war chest. Analysts also say Raila will be on the ballot, with the possibility of backing from the Mount Kenya region following his surprise truce with President Uhuru Kenyatta. “We do not expect the tiger that is Raila Odinga to lose his stripes overnight. We must understand that it’s not salvation, he found he is just reinventing himself as he has done so many many times in the past,” said political analyst Mark Bichachi.
