But at home, his opponents are getting organized.
Among those fighting, Mr Davutoglu and a former finance minister Ali Babacan, both former members of Mr Erdogan’s Conservative Justice and Development Party (AKP), have created new parties.
Coming out of five years in the cold after falling out with Mr Erdogan and resigning as prime minister and party leader, Mr Davutoglu hopes to undermine the president’s loyal support base and help bring down his former friend and ally.
Alongside them, the most powerful players in the six-party alliance are the center-left Republican People’s Party and the Nationalist Bon Party, led by Turkey’s leading politician, Meral Aksener.
The largest pro-Kurdish party, the People’s Democratic Party, or HDP – whose former charismatic leader Selahattin Demirtas is in prison – is not part of the alliance, nor are the smaller left-wing parties.
But all parties share a common goal: to offer voters an alternative to Mr Erdogan in 2023.
Despite their gaping political and ideological differences, the opposition hopes to replicate its success in the 2019 local elections when it wrested the biggest cities, including Istanbul, from the ruling AKP.
“It’s a good start for the opposition,” Demirtas said from prison in an interview with a Turkish journalist. “What is important is the development of a deliberative, pluralist, courageous and united understanding of politics which will contribute to the development of a culture of democracy.”
