This is the exact reason political leaders of all opposition partys declared support for "democracy". It was to cover their asses. People pointing at how low the approval was for a coup are delusional if they think people didn't cover their asses for the inevitable aftermath.
You use the word 'delusional'.
All parties of significance, ranging from Erdogan's political opposition to the military chain of command, rejected the coup. The coup failed, partly, because it had no significant institutional support, and because it seemed to have no significant popular support.
It's a huge step to live under military rule again, and if you feel the 2014 elections were fatally flawed, at least Erdogan was likely the people's actual choice. A military coup is the antithesis of democracy, and the very specter of it undermines the democratic process. To the extent a military coup can be a
good thing for democracy every once in awhile, it wouldn't meet those qualifications here. Erdogan has become increasingly authoritarian over the years, but that's still not enough. Not yet. For one, there's no popular or mass opposition to him; nothing that would indicate the military would be following the general will by overthrowing him. And partly because of that, not only would a military coup be far less democratic than anything Erdogan has done, but it would likely undermine the country's stability significantly.
So when I think of throwing the word 'delusional' around, my instinct isn't to put it on the people who, say, point to the lack of vocalized support for a coup. If I were to put it on anyone, it would be the people who are acting like there aren't massive, practical reasons for sincerely rejecting a coup,
especially for citizens of Turkey.
