How did you arrive at 30 percent?
My MOASS has Raila at 35 percent almost - and he still loses.
The magic number for Raila to beat Ruto by 10,000 votes is 49 percent of GEMA.
Before you throw numbers around - at least pretend to do basic arithmetics.
GEMA remember will account for about 25-28 percent of the national vote depending on the turnout.
Every 10 percent of GEMA is therefore 2.5 percent of the national vote.
Every 5 of GEMA percent is therefore 1.25 of the national vote
30 percent give Raila 7.5 percent boost (roughly 1.3m votes of total expected cast votes of 16m) - hardly enough to cover for losses or gains to/of Ruto in many places -flipping(Bungoma, Tranzoia, Turkana, Vihiga, Kwale, Kakamega) to his column- compared to Uhuru 2013/2017.
And if that GEMA support comes at the price of Kalonzo DPORK - then Kambas become also very hard to consolidate - and could even become battleground.
This thing will be win in gema,that's the battle ground,ask yourself why Ruto is always there.Magic number is 30%.
