They were brothers to boot.
In fact, it was one brother, former president Bingu wa Mutharika, who plucked Peter Mutharika, Malawi's incumbent president, from the United States of America where he had been thing as professor.
And, since his introduction in 2008, President Peter Mutharika has moved on to become Malawi's president, having shrugged off Joyce Banda and her People's Party in the 2014 Tripartite Elections.
However, Peter, too willing to distance himself from the Bingu wa Mutharika who plucked him from near oblivion, has started touting things Bingu wa Mutharika took for granted.
For example, while Bingu wa Mutharika openly made fun of boreholes, saying they were not sustainable, president Peter Mutharika was on Monday all over the sky, celebrating that his government has constructed 12 boreholes under Central Region Water Board.
By all standards, Peter was supposed to be ashamed that a whole water board has reduced itself to a borehole-driller, instead of providing safe, tapped water to people.
Peter's shift is, indeed, ambarrassing.
Bingu wa right and Peter is wrong.
