The defection of former TNA secretary general Onyango Oloo to ODM could deal a big a blow to President Uhuru Kenyatta's re-election bid with only six months left to the general election.
Oloo, the man who spearheaded the Jubilee coalition's spirited campaign in 2013, was also able to make some inroads in the resistant Luo-Nyanza region.
This means that the party is now facing the acid test in the tricky opposition zone, with nominated Senator Joy Gwendo being the only senior Jubilee politician in the region which is Raila Odinga's political base.
Former Rarieda MP Raphael Tuju who is in-charge of the Jubilee Party secretariat is almost 'dead' politically, and can hardly convince anybody from the region to vote for President Kenyatta.
The awkward political dilemma facing the UhuRuto-led party in the lake region may as well be a blessing to Gwendo who has set her eyes on Kisumu East parliamentary seat on the Jubilee Party ticket as she aims to scale up her political career.
The fact that the Senator seems very close to 'wananchi' may make her pull a political surprise and unseat the incumbent Shakeel Shabir of ODM.
However, the Jubilee breakaway faction in the region led by Onyango Oloo may as well shut her political dream even before take off, and leave the perceived ODM zone literally unpenetrable.
For Jubilee, the emerging discontent threatens to give President Kenyatta's 2017 political vehicle to State House a false start and handicap its quest to keep the opposition's NASA at bay.
