In fact, I've seen politicians who are making their image as pro-russian and ultra-anti-russian perfectly hanging out "after work" together, so I don't believe in their play a tiniest bit. Nor do all the rational people I know, of both russian and latvian origin. It's kinda obvious that this theater is oriented towards not-so-educated aggressive minorities in order to gather votes. Normal people just don't care. In fact, we don't care so much that jokes about "wish these effing russians would leave Latvia already!" are perfectly fine amongst our russian friends (which actually surprised me at first, because some 15 years ago people were a bit more radical here). I'm just tired of all this "latvian/russian" thing, I don't really understand what "nationality" or "origin" is anyways. The only "international matter"-thing that bothers me where I live is NATO-soldiers playing war on one of our polygons: you cannot imagine how much noise these bastards make!
Of course I don't really know how things are in Estonia as I don't live there all the time, but impression I've got from visiting and communicating with people who do live there isn't really much worse.
Of course there are Baltic citizens who are not worried by Russia. There are hundreds of thousands of Baltic citizens who are ethnic Russians and do not want to be anything else, after all. And most people they know will be similar to themselves of course, because people on both sides of this ethnic divide live in ethnic bubbles. (Yes, again a generalization that does not apply to each and every person.)
But I would claim that a majority of Baltic citizens, particularly people of ethnically Baltic origin, are worried about Russia (and ethnic Russian minorities are not). At least that's what the election results look like.
