It doesn't matter who it goes for, whether it's Murursade, HG or Abgaal, there wont be any rebellion or anything to unify because there are no Qabiil blocks in Xamar it's totally dead, each of these is with a religious movement that I listed
the PM post will go with Daljir whom Farmaajo promised after they switched last minute allegiance with Shariif because he failed to promise them the PM position, they had influence on 80 or so MP's, it won him the election, these religious groups don't care about Qabiil
The Daljir candidates will be Fiqhe, C/Nasir, Ossoble and whoever else they present to him, hence my prediction it will likely go with Fiqhe or C/Nasir, the latter has paternal relations with Farmaajo and they were good friends in America.
The demographics in Xamar has changed a lot over the last few years, there is a huge Raxanweyne population there and minorities that have moved in. 500.000 IDP's alone in the last couple of years.
I honestly believe if a count was done today, Hiraab all together would be a very slim majority in the city like 55-60% ranges, never-mind Abgaal on it's own who will be a monitory group, so even if hypothetically there was qabiil groups, it would result in a stalemate, this is not the Xamar of 1991-2008.
