The problematic question of who will be president is on the political agenda. Some suggest Ahmet Necdet Sezer ought to hold the post again to prevent women with headscarves from entering Çankaya Palace. Regardless of what is said, choosing a new president will be no easy task.Firstly, Prime Minister Erdoğan's views on this matter need to be clarified and then President Gül's stance on the issue will be of importance. It is too early to tell if Prime Minister Erdoğan has a "Putin-Medvedev" switch type of model in mind. What is evident, however, is that President Gül has no intention of retiring from politics any time soon.Thus journalists feel compelled to comment on the future of Çankaya Palace given that President Gül had a meeting with Prime Minister Erdoğan the other day. Ruthless profession From afar politics look like an attractive exploit, but once in politics it is evident just how ruthless a lifestyle it is. For one person to succeed in politics another person's success must be prevented. Loyalty and gratitude have little place in politics. Those who stride for political success with a sense of humanity intact fall by the wayside.Have we forgotten how those who rose to power thanks to Ecevit then went on to betray him? Do you remember how the circle that Turgut Özal brought into power abandoned him? Weren't Caesar's last words "Et tu, Brute?"When the political and constitutional structures of Turkey are evaluated it is evident that a prime ministerial system exists.However, much as the 1982 constitution aimed to create a powerful presidential post under the watchful gaze of Kenan Evren, was it not elected Prime Minister Turgut Özal who held real power over the state? A two-headed test President Evren accepted this reality and did not attempt to hinder Prime Minister Özal and thus the system worked flawlessly.After the AK Party came to power, Ahmet Necdet Sezer continually utilized the presidency as a blocking mechanism.With Abdullah Gül becoming president and maintaining good relations with the prime minister, harmony was once again restored to the system. In the new era, we will see both a president and a prime minister elected by the public. This current interim system before the presidential system is fully implemented will have its own problems. Just remember how delegates of the True Path Party (DYP) pledged allegiance to Tansu Çiller when their own Süleyman Demirel took office in Çankaya Palace. We'll see what the future holds.
