I am not a political scholar so it never occurred to me that a senator or house of reps member can be recalled. Nigerians have been complaining of bad governance, so why can't they threaten the senators representing their constituencies to do the right things like impeach the president if he is not performing or they get recalled? Why can't this be done? Or is there something I don't know?

We do not know our collective power. Even if few people know, the majority that are zombified will still play along ethnic/tribal & religious line in backing whosoever they like.

Its like u are not in Nigeria. Absolute power rules absolutely. Buhari dead or alive will rule Nigeria till 2019 and nothing will happen
