It was literary guru and eminent academic,
Prof. Okey Ndibe, who formally broached the
issue weeks before the national conventions
of Nigeria’s two major political parties were
held by arguing in an article published last
month that the opposition All Progressives
Congress (APC) is the same as the ruling
Peoples’ Democratic Party (PDP). He wrote,
“PDP and APC are kindred spirits, two parties
beset by ideological aridity and most of their
prominent figures fueled by the same
contemptible idea that politics is, above all, a
means for accumulating riches. Why else do
they hire thugs, kill or maim their
opponents, betray all lofty principles, submit
themselves to the most diabolical rites. It is
certainly not to serve Nigerians.”
This postulation elicited a prompt response
from the Publicity Secretary of the APC in
Lagos State, Mr. Joe Igbokwe, who
vehemently rejected the lumping of the two
parties as one, describing such position as
“a vintage PDP propaganda since they can
no longer explain what they did with
sixteen years oil windfall.” He continued in a
riposte that “Nigeria is wrecked and
damaged and no one knows where to head.
Poverty is rife, impunity is overwhelming,
infrastructures are decayed… With this
dreary picture and with the reality of being
swept off power, PDP came with the
insidious propaganda that it is the same
with APC, the party that stands the greatest
chance of seeing it out of power. With this,
PDP wants to level the ground and make
Nigeria’s case incurable.”
DAILY POST will resist the temptation of
providing insight into fall outs from the
primaries on both sides, lest it influences
your voting pattern. However, we will still go
ahead to ask if from what you have seen so
far or heard of the two major parties in
Nigeria…

Yes there are differences

APC: Conducted A Transparent Democratic Presidential Primaries
PDP: Conducted A Coronation Of A Clueless Emperor Candidate

APC: Has credible Presidential/VP Candidates
PDP: Has an incompetent duo as flagbearers

The differences between the two parties are similar!

In 2 liquid pharmaceutical formulations of same vehicle, the next thing to consider is the active pharmaceutical ingredients(API) base on the risk-benefit ratio!

They're the same, Birds of the same feathers.
The only difference is APC is more desperate judging from the group of people in it's fold.
