My quick thoughts
Dida - crazy, jokester, extremist?
Kiyiapi - soft, above his head
Kenneth - quick on figures, knows his issues
Uhuru - pressured but not averse to the challengea, centre right philosophy
Martha - ideological but some stupid ideas (Satellite?)
Mudavadi - sober but too steady?
Raila - tired, social issues emphasis, deflects criticism
Muite - brusque
Also hopefully sober debate on Land and more details on economic and infrastructure issues in the next debate. More of Linus and his direct line of questioning, less of Julie's church meeting style. Also fewer candidates, let the high court hear the case and give an answer before the next.
