Yes for most political decision or contribution there is an economic undertone. This contribution to this political campaign might be a "Greek gift" to attract favor or political patronage ones Mr. Obi becomes the President. Google about this Presidential candidate and you would discover that he has the largest youth support base. Many youth are contributing as low as $1 to ensure that they support his campaign. He is perceived as an incorruptible, youthful and a visionary leader. The good-news is that regardless of the intentions of the donor or the recipient the message of Bitcoin is being preached and publicized.
It is clear it was not given out of love for the aspirant or to support a wonderful cause. It was given to either gain political favour or create awareness to his tactcoin so the rest of Nigerians will think the coin is approved by the government. (People can read different meaning to things especially the less educated ones. )
I hope this Peter obi of a man is a btc support and have a soft spot towards digital currency in general.
