You can't compare the two. The only state in Somalia HG have a majority is Galgadud. The MJ in Nugaal alone are more than all the HG in Galgadud. Same goes for the MJ in Mudug and the HG. This is all without counting Bari. People think that the numbers are close, but looking at the most recent census it is not really.
There is no actual political competition between the two, HG will not become PM or President anytime in the near future. Abgaal stands in the way of the presidency, and if an MJ become president a HG will never be appointed. The clan that is actually in a struggle with HG is Abgaal wo are hogging all the power of the Hawiye to themselves.
