Collapse unviable states into another atiku

A reference to the 2019 Nigerian presidential election!

In that election, Atiku Abubakar, the candidate of the Peoples Democratic Party (PDP), lost to Muhammadu Buhari, the candidate of the All Progressives Congress (APC). Atiku had won in 19 states, while Buhari won in 21 states.

However, I assume you're asking me to collapse the 19 states won by Atiku into one, which would mean that all the votes from those states would be aggregated into a single state. If that's the case, I can do that for you.

Here's the result:

Atiku's Collapsed State

Note that this is a hypothetical scenario, and the actual results of the election remain unchanged.
