Fayose said the 75-year-old president will be easy to defeat at the polls next year.
President Buhari ended months of speculation when he officially announced his intention to seek re-election in the 2019 presidential election during a meeting with the National Executive Committee of the All Progressives Congress (APC) on Monday, April 9, 2018.
Governor Fayose, who is also contesting in the presidential election, said the president is old and tired and Nigerians will be glad to vote him out.
While expressing his views on his official Twitter account (@GovAyoFayose) late on Monday, Fayose said the president is easy to defeat due to his failures as president since he was elected in 2015.
He posted, "Buhari has done more harm to this country. His ambition is a means by which Nigerians will tell him good riddance to bad rubbish when they boot him out of office. He is an easy candidate to defeat in the poll because he has failed woefully.
"That second term ambition of President Buhari is dead on arrival. We don't want Grandpa as president anymore. Nigeria does not deserve a Buhari as president in 2019. He is old and tired. When people don't know when to take their leave and say bye, Nigerians will show them the exit door.
"Buhari has failed in all fronts. He has failed in his so-called fight against corruption, he has failed in the economic front. He has not done well in term of security. Gruesome killing of Nigerians is now a daily occurrence in Nigeria."
A lot of public reactions has trailed the president's announcement, with former Minister of Education, Oby Ezekwesili, comparing him to a trespassing masquerade who doesn't know when to stop. She said the president's second term ambition will spell the end of his reign as the nation's leader as well as the end of a "decadent political class."
In the official reaction of the opposition People's Democratic Party (PDP), they said the president's announcement is nothing to talk about until he wins the APC's nomination.
Motivational speaker and leadership coach, Fela Durotoye, became the second aspirant to officially declare his intention to contest for president after he joined the Alliance for a New Nigeria (ANN) on February 22, 2018. Omoyele Sowore, the publisher of online news platform, Sahara Reporters, declared his intention to run just days later on February 25.
Fayose, was the first aspirant to have officially declared his intention to contest after his announcement in September 2017.
A former Deputy Governor of the Central Bank of Nigeria, Prof. Kingsley Moghalu, Lagos-based businessman, Ahmed Buhari, and IT entrepreneur, Adamu Garba II are also in the running.
Former Vice President, Atiku Abubakar, is expected to be President Buhari's biggest challenger after he left the APC and moved back to the PDP.
