DJQuag,
Was the coup right or wrong? I do think that we should weigh the opinions of virtually every political party in Turkey, on the right and on the left, they all came out against the coup while it was in progress (and Erdogan was outside of the country and looked to be losing).
And I think it is noteworthy that the population at the urban centers (Istanbul and Ankara) came out into the streets in defense of Erdogan and the democratically elected government - in general, the urban centers are where opposition to Erdogan is strongest. While it is theoretically possible this was all staged, I think it is unlikely that you could have that many people involved in a pre-planned activity without someone spilling the secret.
I think that Erdogan is not a good ruler, there is more than a bit of Putin in him, he is suppressing the press, and it looks like he is using the coup to retaliate against perceived opponents, including those who had nothing to do with the coup. But he also was democractially elected and appears to have popular support, and we have overlapping areas of interest, such as Russia/Crimea/Ukraine, the Caucuses, Syria/Iraq, Iran, etc., which makes this a challenging case for US foreign policy.
