What concerns the national assembly whether or not little known parties win seats? How does that affect anything?

The only reason is anti-Buhari agenda.

Buhari is a movement in the entire northern states and if these corrupt lawmakers succeed in rigging him out of office, expect an explosion of anger from the northern masses, who are the most politically sophisticated group in Nigeria. Expect many mansions ans convoys of northern politicians to be attacked and set ablaze.

But that shouldn't affect the results of the elections even if people lose interest.

There is basically no reason for the reordering other than a selfish agenda by some corrupt APC federal lawmakers and governors to work to prevent the president's re-election once they have secured their own re-election.
