The defection of Ugenya MP David Ochieng from Orange Democratic Movement (ODM) to the Movement for Democracy and Growth (MDG) could pose a serious threat to his old party if voters in the region go against the formbook and vote for a candidate from a smaller political party.
The region has previously demonstrated a stubborn independence and voted for leaders outside Raila Odinga's ODM when they have felt their choice of candidate was being unfairly pilloried within the Orange party.
