Turkey has one major flaw and that is the opposition is divided among many smaller parties and they have problems coming together on many issues. The protests can build momentum but like many other movements they might fall short because of the lack of common grounds. That is the same problem as it is in Russia where ultimately people feel that voting someone else might lead to unstable alliances and society collapsing. Not saying this is true, but for many in these countries it is the realty they perceive.

And I didn't say that no Kurd with Greek sympathies couldn't be elected. Simply stated that it is unlikely that it would be a strong enough view to change their relation. At least not in the short to medium time span. AKP's majority and ability to dominate Turkish politics, society and media is a force that the current opposition has a tough time dealing with. During AKP reign there has been prosperity for many and unfortunately many people are willing to trade freedoms for economic security. And Turkey before the AKP didn't offer economic stability.

PS. Don't support the current regime in Turkey and support the idea of openness and democracy, but as someone outside of Turkey, their is little I can do persuade those supporting AKP because of the positive accomplishments to the average Turk. Especially since the opposition is so divided and doesn't seem to be able to combat in uniform against the current regime.
And Syriza's coalition partner is not going to help with this.
