RIZE, Turkey – Beaming down from a three-story-high red banner over a main shopping street, the local boy who rose to the heights of power, Recep Tayyip Erdogan, urges the residents of this Black Sea town to "come on, lay claim to your president."
For more than a decade, Erdogan, 61, has been the dominant political figure in this country of nearly 80 million, first as prime minister and since August as president. Sunday's general elections will determine whether the man already accused of autocratic rule becomes still stronger.
Should the right-of-center, pro-Islamist Justice and Development party he founded win an absolute majority in the 550-seat Parliament, it intends to amend the constitution and turn his figurehead post into a more powerful American-style presidency.
But the "claim your president" banners, seen in many places around the town where Erdogan was born, offer signs that he has jumped the gun.
These are parliamentary elections and he's not on the ballot. Under the current constitution, he's supposed to be politically neutral, so every poster linking him with the vote or with Prime Minister Ahmet Davutoglu, every public appearance in which he takes sides, adds to the case his opponents are making that he has violated the constitution.
But Erdogan has turned this into a referendum on himself. And while there's almost no chance his home region will vote against him — in 2011, it returned three members to Parliament from his party, known by its Turkish initials, AKP — the race here provides indications why the country may hold back from giving him the supermajority needed to revise the constitution.
Unhappiness over the country's uneven economic development and disquiet over a corruption scandal that Erdogan has done his best to suppress motivate his opponents.
Kurds could be spoilers
Chief among them is the Kurdish People's Democratic Party, or HDP, which is running in national elections for the first time and can upset the Erdogan applecart if it receives 10 percent of the vote and enters the Parliament.
