You're getting ahead of yourself. First Uhuru trying to extend his rule in anyway will be resisted both locally and internationally. It will be such a bad move - he should never entertain such thoughts.
Now let get to basic. I don't understand why Uhuru would go out of his way to give us a lame BBI - and then spend the next six months trying to square cycles - and hold a referendum like Orengo wants in six months. That is pure laughable madness.
Now I know everyone apart from Ruto wants to have bigger executive so they can share power. So yes BBI promising more jobs will be popular. I don't think Ruto will oppose it if it comes the vote. Whether it's parliamentary or presidential - the rule of the game do not change - someone still has to have larger party or coalition or votes. That is where Ruto really need to focus - and opinion polls so far suggests he is doing very well.
Ruto job like I have repeatedly said is to buy time and ensure the constitution doesn't get changed.
He is doing well so far. We have 2.5 yrs to election in 2022.
I am not sure how practical it is for :-
1) Pro-BBI team to meet and agree on BBI 2.0 - I know you think they will buy you 'genius' ideas but nothing suggest they would. The team just got gazetted. Let assume they will take the six months - to do another round of pretend data/views collections - to come up with 'New Consensus' document or Constitutional Amendment Bill.
Risk No 1 for BBI 2.0: Our judiciary could throw a wedge on that - our judiciary is free for all - some are fiercely independent - some are corrupt - Uhuru certainly has no control that is why his election was annuled and he is not seeing eye to eye with JSC & Maraga.
2) Then assume we Robina Constitutional Amendment Bill ready for signature collections in Mid June - and Kibicho deploys provincial administration to collect 1M signatures - in a month.
Risk: Judiciary could stop or declare such signature collections null and void.
3) Then IEBC whose jobs are on the line - are suppose to take 3 months - to verify. You cannot squeeze IEBC time on that.
Risk: IEBC could reject the signatures like they did to OKOA or the process could end up in court.
4) Let also assume Uhuru's manages to convince Ichungwa and parliament to add referendum budget for IEBC.
Risk : Parliament might refuse to find budget for uncontested referendum.
----We are now in 2021 --- election campaigns are catching up fire --------------- Uhuru is now officially a lame duck.
5) Let also assume that IEBC verify the signatures - and now counties are given 3 months to deliver their verdict to IEBC.
Risk : 24 counties could fail to ratify this or well judicial fight.
6) IEBC submit the bill to senate and parliament. Parliament either passes or oppose or sits on.
Risk : Parliament sitting on bill. Duale only wants to be the PM under Ruto presidency - he knows anything else is a pipe dream.
7) IEBC to conduct the referendum and we go for yes and no.
Risk ; IEBC has not funding.
: Referendum results are contested - judiciary either accepts or annuls.
Bottomline; For Uhuru to undo the constitutional limits he will be killing a lot more people.
BBI 2.0 remain the big card yes. From endless praises of the process in Jan 2020 Uhuru seem very determined. Taskforce was extended and Raila is onto the legwork. It laughable to claim Raila-Uhuru combo would have any difficulty fast-tracking the process - 1m signatures (joke), IEBC (joke), 24 counties (joke), parliament (joke). MPs are Judases who only care about their interest as you saw Duale back parliamentary and desert Ruto in the hour of need. Parliamentary is very hard to beat in non-GEMA. With Speaker Muturi and the minority leaders and maybe even Duale it impossible to block or "sit" on the bill. In any case you don't even need numbers just a rejection and it roll over to referendum. Tough luck beating parliamentary and more devolution on the ground.
Kiunjuri and GEMA - Uhuru looks ready to persecute Tangatanga and keep them out of Mt Kenya. Look at Kuria lock-up and Susan Kihika in Nax. From the warnings of Kinyanjui and wa Iria about folks disrespecting Uhuru will not be allowed free reign in the mountain... it seem Tangatamga will face it rough. It very easy to kick Ruto and Kiunjuri out of GEMA especially Kikuyu. Now with all the goodies for farmers you see it will be hard to sell Ruto when Nyoro and Kuria are physically barred from holding rallies. Uhuru seem ruthless Moi-Jomo not lame Kibaki - I think you have mistook his silence before for weakness.
Jubilee & power levers - Uhuru has the GoK machinery yes. He also control judges through intimidation when push come to shove. Presidential run-off comes to mind - they brazenly executed Philomena Muilu driver and ensured there was no quorum. Judiciary is only independent when there is no dirty war. But a determined PORK can manipulate them with his NIS and other tools. Parliament you can save it please - MP allegiance depends on interests. In the case of BBI/parliamentary Ruto is in the minority. Jubilee Party of course is a conundrum. PORK has the muscle to either block the polls or mess with them altogether by forcing his guys in. This Imperial PORK can do anything... see all these intimidated governors have all lined up behind BBI. If he can lock DPORK out of his official residence - what difficult about kicking him out of the party? Ironially it is reforming this same Almighty PORK tha you vehemently oppose? It self- defeating.
Uhuru will likely enter a coalition with Raila and Kalonzos/Mdvd crew as Party Leader - ahead of 2022 before or after referendum - and Ruto has no shortage of choices for party. Tanga Tanga Party, United Green Movement, name it. Problem is against Uhuru-for-PM and Raila running circles in non-GEMA - it will be a mountain for him.
What Nyahunyo can he really unleash when he is becoming lame-duck everyday. Maybe he unleashes an assassination squad otherwise as long as the GEMA people are anti-Raila he is wasting time, energy and strategy. I think Kiunjuri need to take war to him now. As for Lee - he knows his time is up - and Kihika daughter will sweep the floor with him & Mbugua. Nakuru is the const you want to least annoy Ruto because Kalenjin makes nearly 40% of the vote (if not more).
As of now Uhuru has executive authority - Ruto has parliament - and Judiciary is out there. Ruto has the Jubilee party and majority support of Jubilee members.Anyway let see first how Jubilee elections will go. Then we get BBI 2.0. And then we take it from there.
Ruto best strategy is to bid time - to survive 2020 - and then 2021 it full campaign mode - and Uhuru will be forgotten - as lame-duck failure (farmers failure is a shadow because his big 4 is becoming a BIG JOKE) - as Raila get blamed for messing up Jubilee and hustler narrative is unleashed.
Ruto just need to ensure the constitution is not amended (increasingly becoming impossible - considering the timelines needed to come up with new constitution - have BBI2.0 come up with executive pm in parliamentary system - we can live with that , collect 1m signatures, have the signatures verified by IEBC, have the bill prepared approved in 24 counties, have it go to parliament for a vote (or to be sat on) - both houses, have it frustrated by judicial injunctions along the way with Omtaha already on it, have IEBC funded to conduct the referendum)-
Ruto should avoid attacking Uhuru directly - Just deflect and attack Raila. Continue with shadow boxing - until Uhuru makes it clear - via constitutional referendum that he is in the ring - and then Ruto can stop pulling punches.
