I analysed after watching in high speeds, and I summarised the whole charade in few sentences:
Sabina Chege is the one making valid points, and it seems politicians from the mountain are trapped and don't really know what mountain voters want at this time, hence the confusion on which party to join with certainty. Some wants to be in Jubilee, others in DCP, and the rest in UDA because they can clearly see UDA is good for them and the country in development/issue matters.
Gakuya is demented like Gachagua and wants Kikuyu to stick together in voting against the system for grievance reasons, not development/issue reasons, aka Tumbocracy. DCP wants to unite the mountain first instead of nationalising the party first like the way UDA did. You want to build a strong national party, start far away from home, and home will slowly come to fold. DCP should be busy spending money in Nandi, Bungoma, Mombasa, Garissa, Turkana, UG, Samburu, Narok, Mandera, Baringo, etc., funding women's groups/boda boda, youth groups, church groups, mosques, etc., and funding local politicians, nyumba kumi leaders, etc., while selling policies like universal healthcare, housing, economy revival measures, and how to actualise them when power is acquired. That is how Ruto did with UDA relentlessly for 5 years, and RV automatically came to fold without much effort. I think DCP doesn't have money and a solid plan and structures to pull such a thing, only grievances and tribalism for now.
It will be very hard dislodging UDA nationwide, even in areas close to the mountain, especially if there are too many parties there. Places like Nakuru, Laikipia, Lamu, Embu, Meru, Tharaka Nithi, and Nairobi, where slum dwellers have seen impacts of affordable housing and Ruto's plans to move 7 million slum dwellers to better living conditions. Millions can see Ruto's work while politicians, especially DCP, are busy with kingpinship and tribal politics!
