Sonko, Waititu, Uhuru, Ruto already got elected - the people decided in 2013, 17.
The same people elected assembly and senate who impeached Sonko, Waititu. Noone stopped the two from running to high court, CoA, SCORK to overturn the impeachments - but the 14 days appeal window is gone now so their fate is sealed.
The very Wanjikus voted Cok2010 judges - who cleared Uhuru, Ruto to run. If ICC senior magistrate Ekaterina had convicted Uhuruto - and appeal chamber upheld or they fail to appeal within legal window - they would lose their presidency. And become permanently ineligible.
See? No confusion. Appointed official get fired or step down immediately - elected must get convicted first and exhaust appeal. In fact Pundit - since MCA, MPs and senators are elected unlike judges - they have the right amount of mandate to politically convict - and you still get to appeal.
That LET THE PEOPLE DECIDE is slippery slope. The people can also elect a foreigner or Al Shaabab. There must be standards.
