Ahead of Sunday's elections, a cost of living crisis is now hitting Erdogan's support in the southeast as elsewhere, threatening his prospects in a tough battle to maintain power.
A survey published this week by pollster Rawest showed 76.3% support for opposition presidential candidate Kemal Kilicdaroglu in Diyarbakir province, with backing for Erdogan at just 20.5%.
The Kurdistan Workers Party (PKK), deemed a terrorist group by Turkey and its Western allies, took up arms against the state in 1984.
Those talks collapsed in 2015, unleashing a period of ferocious urban warfare in the southeast, including in the streets near Aydin's shop.
CHANGE IN ERDOGANThe HDP, parliament's third largest party, has itself declared its support for Kilicdaroglu.
