There is a lot those bought Mps can do btw now and 2022. Ruto is DPORK - he is powerful and untouchable because he controls parliament. He also controls half the gov. Now when it come to 2022 - Ruto has to navigate the referendum and ensure it become stillborn. The first step is to block in via judiciary. If that fails, block at MCA level (they need 24 county assemblies). Then next is to stop it parliament. Then have it go through a referendum of collecting and validating signatures.
Uhuru has been shadow boxing Ruto. If he comes directly - Ruto will also go directly. The idea is here is to get Kiunjuri or Speaker from Embu or GEMA person who is not ready to serve under Uhuru forever - and want to take the war on Kenyattas. I think Kiunjuri has the conjones to do that.
I believe referendum cannot go through even MCA now. Ruto has iron grip on 14 RV counties - he has iron grip on another 6 counties of pastoralal communities. That is already 20 counties. He only need to win 4 counties ( He has 4 to pick from Coast), maybe 1 or 2 in Western that can sway and maybe 1 or 3 in Eastern (Embu, Meru, Tharaka), and even 1 or 2 in Central that can go rogue.
