Your double standards and hypocrisy reeks!
Why havent you included Raila, Babu Owino, Uhuru, and all the bad leaders in Azimio:)
Parliamentary system cannot fix leadership - the same crew in parliament will elect Sonko.
Mayors were worse than governors.
In fact presidential system is better because it very hard to bribe millions of voters.
Leadership come from the people.
You need to focus on improving leadership in all levels - over the time.
Right from quality of DIP chairman or ECD chairlady - I remember during my childhood my mum was elected chair because rest of women were basically illiterates.
That will slowly permeate through the society in sustainable way.
Europe and rest of developed world have over the years improve their leadership..
