To avoid the Kibaki and 2013 Uhuru problem, the riggers had to also interfere in the MCA, MP, Senate, Gubernatorial elections as well. That way there would be no "deficit" of votes.
Now that is widespread. They went as far as Kitui, Kisauni etc.
The level of interference is such that the entire election is damaged beyond repair. An organ that is got more cancer cells than healthy ones is usually considered for removal. It can not be medicated.
