Change was achieved by the constitution which the best path was parliamentary but sadly turned out a purely presidential. The rest are details as you cannot tell us "change" will only happen once your hero wins. Raila supported the pure presidency that entrenched the tyranny of numbers; chiding them now is hypocrisy. He praised Mutunga (after thwarting Vishram) and went cobra on him after the petition. He claimed during the campaigns that he was best placed to implement the constitution as UhuRuto were watermelons; he now has a prime minister. If Jubilee loses, Ruto as opposition leader would demand all kinds of "reforms". If Ruto wins in 2022 and mistreats Kikuyus, they will swiftly join the "change" bandwagon.
Nothing new under the sun. Sorry I don't believe in any change except the one that stops ruling class impunity. Wait a minute, noone is promising this one.
No, Kenya will not explode. One of two things will happen.
1. Uhuru wins - NASA cries rigging. Expect riots and teargas. In a few days Kambas then Luhyas abandon Luos to a lone cause
2. Raila wins - Uhuru goes home, Ruto becomes opposition leader. Kikuyus await the decree condemning them to short trousers & slavery. Luos await manna & free housing. Both wait in vain
