I'm expecting he's going to win the general election later this year, as much as he's hated, I don't see him being replaced. My belief is that Abiy is double downing on the Grand Renaissance Dam and the few port deals he has going. Before ethnic tension implodes the country into chaos. Hear me out for a sec.
Berbera Port has seen extensive development lately and the roadwork is progressing. This port will be of considerable help to Ethiopia when it's fully functional. Ethiopia offered to develop a new port in Sudan earlier this year and Sudan agreed, this is a big win for Ethiopia. There's talks of building a rail connection to Eritrean ports, nothing has come to fruition as of yet though.
Couple this with the Grand Renaissance Dam nearing completion, that's forecast to annually generate ~16,000 GWh when it's reservoir fills. The reservoir that forms, Millennium Reservoir, is expected to have a volume 3x that of Lake Tana. They're expecting to have a lot of fish there too, they're forecasting about ~7,000 tonnes annually. Along with the potential to make the area a tourism hotspot.
We could be seeing a very different Ethiopia in 5 years time. It's how I'm beginning to see it as; a race against time for Abiy. Get these projects to work and align. It's the only explanation I have for how he's moving.
