Maybe marginalisation is partly to blame. But most of those Luo leaders (actually all of them) used Baba to clinch those seats and then instead of serving people, they served Baba and their own interests.
Some of us wanted Baba to win the AUC seat because it meant exiting local politics. With him out of local politics, those hanger ons would've found it hard to get elected and maybe the Luo nation would've had an opportunity to elect fresh leaders. Leaders who didn't cling on Baba for woishe support.
