You better leave Kenyan politics to those who can analyze it without being nonsensical, while adding and equating out of this world figures and ludicrous percentages. Such alliances aka G7 are evil, most of those in that group are thieves and have ill-gotten wealth. So they are congregating to try and form a formidable wall to fortify themselves and their impunity/corruption. But, thanks God such politics in Kenya is deeply fading away. The more they realize it the better and seek for reconciliation with the members of their constituencies. The new constitution, with goodwill ambassadors like Minister for Justice, will make sure that the waves against impunity hit hard. G7 is a Ship like Merriposa Belle, everyone is looking for a position to scamper and hide but, too late people have been indicted, but still think there is hope. It is only a matter of time that these guys will try to knock at other parties. Kenyan politics is complex. If you have no clue how to analyze CCM vs CHADEMA politics, how will even understand the politics of Kenya?. This is not CCM and CHADEMA "cut-throat" family politics. This is about policies, peace and trying to heal the nation's past from a historical standpoint.
I am amazed that you being non-Kenyan, can mention the Kenyan tribes Kamba Kikuyu boldly. Maybe you are a son to a professor of a university. OR you may be Working in a Government institution and may enjoy full benefits . You may not understand why peace may be an important ingredient to those who may not enjoy the benefits of such Like alliances/Hateful politics of G7.
