I was in Sevastopol last August talking to the locals and counting more Russian flags flying than Ukrainian ones.
Of course, what do I know? I've only been to Crimea and the Donbas four times in the past 8 years, married into their culture and speak with people residing in eastern Ukraine on an almost daily basis.
Perhaps your many visits to this region and your interactions with the local populace have been different? Please share.
Presumably you are not a professional pollster who was polling everywhere in each city in Crimea:
Moreover, in a more recent Razumkov Center survey (from December 21-25 2013), while substantial minorities endorsed either Crimean independence (35 percent) or joining “another state” (29 percent), a majority (56 percent was opposed to either of the political options involving Crimea’s separation from Ukraine. Of course, it is anyone’s guess how these proportions have been affected by the events of the past two months in the context of a highly partisan political and informational environment.

There was a greater degree of support for annexation in Crimea than anywhere else, but not the 90 or so percent with alleged "record turnout," which would mean that the Tatar population voted en mass to be annexed too.
