The ruling party had fixed June 22 for the exercise.
On Monday, the APC adopted direct primary.
Also today, Obaseki presented his Expression of Interest Forms to President Muhammadu Buhari at the Presidential Villa, Abuja.
After the meeting, he spoke to State House correspondents about the election, his predecessor, Adams Oshiomhole, and his rival, Osagie Ize-Iyamu.
The governor said he visited the president to formally inform him and solicit his support.
Obaseki disclosed that Buhari was welcoming when he showed him his forms.
“He looked through it and teased me that he will not have to go through this again, he wished me good luck and assured me his support.”
Obaseki stated that the APC crisis in the state “is not from Edo but from outside. The person I am contesting against (Ize-Iyamu) is not in Edo, he is in Abuja.
On Oshiomhole, APC National Chairman, Obaseki said the former governor took his current position because he was not properly guided.
He assured that he will continue to pursue peace for the sake and interest of Edo people.
Confirming that the relationship is still frosty, Obaseki said he was doing his best “to try and make it warm just for the sake of Edo people. Whatever it will take to have peace, whatever it will take not to lose lives in Edo, I am committed to.”
Obaseki added that he has the endorsement of APC Governors.
He said all of them had decided and agreed that “when you have an incumbent governor particularly if he is doing well, they should run around and support him. It is a common practice all over the world”.
