This candidate has not broken any law except he ran against the dictator and got over 10% of the vote. And he is friendly to Kurds. It is common in Turkey to build a coalition government because normally no one wins the majority directly.
Now, with Erdogan the Islamist as the dictator with his emergency powers he can arrest whoever he likes and if he does not like how the court rules, he overturns the judgment and fires the Judge.
How is that for a system?
Maybe they should give them the George III treatment.
