From a Zogby poll of public opinion in Egypt, from this September:
A plurality (46%) of all Egyptians believe that the situation in their country has become worse, not better, since the Morsi government was deposed. Eighty percent (80%) of FJP supporters express this view. But only about one-half of the rest of the country feels that Egypt is better off, with nearly one in five saying that the situation is the same as it was before the military intervened.
The military remains the institution in which Egyptians have the greatest confidence, but their positive rating has declined to 70%, owing to a sharp drop in support from those who identify with the Muslim Brotherhood’s FJP and a slight decline in support among liberals and those Egyptians who associate with none of the country’s parties.
The country is split down the middle in its view of the military’s July 3rd deposing of the Morsi government. The FJP, of course, is unanimous in finding the military’s action incorrect, while almost two-thirds of the rest of Egyptians support the deposing of Morsi.
With the caveat that polls in Egypt can be unreliable, this suggests that coup-skeptics are more numerous than imagined – but perhaps too intimidated by pro-coup propaganda and the ongoing crackdown to go out and demonstrate about it. And it's not about being pro-MB, either, or anti-military.
