Osinbajo launches door to door campaign in nyanya karu roots for buharis re election

I think there may be some inaccuracies in your statement.

Firstly, Osinbajo is the Vice President of Nigeria, not a presidential candidate, so it's unlikely that he would be launching a door-to-door campaign for Buhari's re-election.

Secondly, Nyanya and Karu are both local government areas in Nasarawa State, Nigeria, not a specific location where a campaign would be launched.

Lastly, while it's true that Buhari is the current President of Nigeria and has announced his intention to seek re-election, it's not clear if Osinbajo would be actively campaigning for him.

If you have any further information or context about this statement, I'd be happy to help clarify things!
