It could be quite similar to DS9 and that's liked.
Could be cool too if they focused on other species' governments too, intercutting.
Star Trek is about flying around in space and encountering weird shit. Dudes stood around on Earth chatting is the absolute opposite of everything I want to see in Trek.
There's always been politics. They could do so much more with the weird shit though, than they already have. No limits there really.
