Since the emergence of Speaker Aminu Tambuwal
as the governorship candidate of the APC in
Sokoto State, it appears some members PDP are
now pitching their tent with the APC, moving
forward.
About 3,000 members of the Peoples Democratic
Party (PDP) in Isa local government of Sokoto
State on Sunday defected to the All Progressives
Congress (APC).
Umar Mohammed Wali, the local government
caretaker committee chairman, who disclosed
this, stated that the PDP members took the
decision to join APC not out of any compulsion
but with the conviction that the APC is the
expected liberator Nigerians have been longing
for.
He aid the defectors, who are from the local
government of Ex-governor Attahiru
Bafarawa, now a chieftain of the PDP in the
state, defected to the APC because they had
seen that Bafarawa had lost his political grip
of the masses and his kinsmen.
According to him, Bafarawa and his political
mastery is now past tense as far as they are
concerned.
He assured that APC had not only stamped its
feet on the land but had equally overcome any
challenges ahead of the forthcoming election.
On his part, Governor Aliyu Wamakko, who was
represented by the commissioner for agriculture,
Alhaji Arzika Tureta, assured the defectors of
equal treatment as justice remains the watchword
in APC.
Wamakko further advised other local governments
in the state to emulate the defection wave which
had just begun from Isa and will subsequently go
round the entire state, hence they have seen that
APC is the only hope for Nigerians.

It's for their safety. The North is rapidly becoming APCized by the day so it's not uncommon.

P.S: I'm no TANoid.
