He said like the governing National Democratic Congress (NDC), voting for the main opposition New Patriotic Party (NPP) is a win for their families and cronies and not for the ordinary people of Ghana.
He said Dr Bawumia has overnight concern for the people of the North following his nomination as the running mate to NPP Presidential candidate, Nana Addo Dankwa Akufo-Addo.
He described Dr. Bawumia as an "Accra Northerner" because despite hailing from the Northern Region he does not understand the hardship of the people.
Dismayed by the level of poverty he had witnessed on his campaign tour, he said Dr Bawumia despite several opportunities to help his people, found his voice only after he entered politics.
"Where has he been all this while" he wondered and said had it not been for politics, Dr. Bawumia would not have been promising the people of the area improved roads and better healthcare.
Politicians are falling over each other trying to demonstrate to the voters in the three regions of the North that they deserve their vote.
While on a four-day tour of the Upper East region, Dr. Mahamudu Bawumia, accused President John Mahama of destroying the 'Northern brand'.
He said through the President's actions and inactions, the brand, which was known to be one of integrity and honesty has been soiled.
Speaking at Balungu in the Bongo Constituency last week that, Mr Greenstreet said “John Mahama’s government is the most corrupt government in the history of Ghana. Dollar for dollar, cedi for cedi, this government is the most corrupt in our history. And yet he tells the people of the North to vote for him because he is our brother.
"Why does your government steal from Northerners if you care for Northerners and why do you want us to give you another opportunity to steal more from the people you say you are trying to protect?” he quizzed.
President John Mahama also courted controversy after he told voters in the three regions of the North to reject NPP because nobody from the region can ever be president on the ticket of the NPP.
Mr Mahama noted the reverse is the case with the National Democratic Congress (NDC) where the party’s National Executive Committee took a decision and made him the flagbearer.
‘‘Who am I a boy from savannah Bole born in Damango to stand here today and call myself the president of the republic Ghana? NDC is the party that is the most national in scope; it is the party that opens its opportunities to all Ghanaians irrespective of where your ethnic affiliation is.
"Sometimes I feel sad when I see some of my northern brothers running around and also doing this [supporting them]. They will use you and dump you,’’ he said at Jirapa as part of his campaign tour of the Upper West Region.
