The mechanics of a rotational presidency are somewhat complicated from my perch. The question of what criteria one uses is the one that keeps cropping up.
If Okiya refers to an electoral college kind of thing, that makes sense in a divided country like Kenya. Electoral college forces one to try and appeal accross a wider cross section of the country.
That said, all these changes are meaningless with an intact IEBC. I think they should also push for devolved electoral boards.
