The answer is Abuja.
Dodoma is the capital city of Tanzania, and similarly, Abuja is the capital city of Nigeria.
Prior to Abuja, Lagos was the capital city of Nigeria. However, due to its rapidly growing population and other challenges, the government decided to move the capital to a more central location in the country, which is Abuja.
Therefore, just as Dodoma serves as the political hub of Tanzania, Abuja serves as the political center of Nigeria.
