Please why are we Nigerians trying to misrepresent facts, the fact of the Katsina and Bauchi incident? as am stating right on this forum, PDP members from the north are deceiving Jonathan hiring crowds not minding who they recruits for rally but unfortunately for them the crowds decided to show who they actually supports when they reach the rally grounds, if the PDP leaders in the north doubt this let them walk on the street there youths are angry because the have seen that this people represent the self and don't care about there life and the more they keep recruiting fake crowds the more they will be embarrassed by there angry youths. How would an opposition members have the guts to come inside the crowds of mainly PDP supporters? It means they were recruited to come and show solidarity but it back fired

PROF Sunday umah
Every body hires a crowd even the south and west . Do you think every person in the west will vote for buhari

Matthew Sule
To God be the glory, Majority in South West will surely vote for Buhari and Osinbanjo by 14th Feb.

Look when you are hiring crowd then is called contract with the individual hired so if there is breach of contractual agreements why blame opposition? Is it the opposition who recruited them for the PDP leaders? This Is anger from the youths that are frustrated and extremely angry with there political leaders who was never there for them when there were brutally killed by Boko Haram so if the so called PDP leader can not even show up in his state to console the people during attacks all they do is sit in Abuja and talk on pages of news papers now is when the northern youths are telling them in clear language they are not there leaders so they should not pretend to be one.
