I have seen people claiming Western polls are wrong across al sorts of spheres for decades and almost always I find that the person claiming the polls are wrong has some political motive and the polls are later vindicated with a move to free, fair, monitored elections on the same questions. Western polls are pretty accurate. Modi is popular, Hasina is popular, Erdogan is popular, Crimeans in 2014 wanted to join Russia... all of these things are likely true.
