Regional 3tier and hybrid NARA - bad ideas. Pure Exec PM and 40% majimbo - big tick. We will know this as soon as end of Oct or thereabouts. This is what i care about more than Uhuru, Babu or Ruto. I rather Ruto wins as first Exec PM. Than Babu wins as imperial 5th president.
Mt Kenya support - and BBI fate - entirely depends on Uhuru. If he is slated for Exec PM - Gema will fall in line. Keep your fingers crossed.
