ex-USSR?
There is no Estonia, Latvia, Lithuania, Moldova, Ukraine, Azerbaijan and Georgia; therefore there are Albania, Spain, Switzerland, Macedonia, Cyprus, Malta and San Marino. And somehow you deduce it with ex-USSR countries?
Ooops, true, we are talking about Armenia, so they for sure won't go to other Caucasus countries if we take into account their history. On the other hand, Baltic countries have recently switched to the Scandinavian block, so here is why they don't promote their song there. Basically, all the listed countries where Armenia will promote their song are those that are politically less biased/hostile towards Armenia. My argument for deduction is futher elaborated below, so please, continue reading there.
There's events like this in the Netherlands (the biggest one), Latvia, the UK, Israel...that really isn't any kind of argument
Although you disagree, I think that the list given by LesterMalvo actually corroborates my argument which I must now more carefully put in words. Usually everyone here complains that Russia profits from the block voting - which is actually true. However, in the case of Armenia we have a clear proof why other countries do not profit from this block voting as Russia does. Namely, since Russia maintains good relations with almost all of ex-USSR countries (and in the case of those with which they don't, they can always count on the votes of Russian diaspora), and consistenly in turn "rewards" them with high points (I hope you have noticed that Russia always give high points to almost all ex-USSR countries, but every year to a different country), they secure themselves a good deal points. On the other hand, other ex-USSR countries do have a lot of issues among themselves, (for instance Armenia, Georgia, and Azerbaijan are very unfriendly one to another, while Baltic countries distanced themselves too much from their recent "brothers") which is why they all lose points that Russia so diplomatically manages to get them. Basically, what I am trying to say is that Russia (and until recently also Ukraine, but let us see what happens with Ukraine this year = how the other ex-USSR will react to their new relations to Russia) as a matter of fact because of these internal "disputes" between other ex-USSR countries profits even more from this ex-USSR block voting as it would if other countries were in better relations between themselves.
On the other hand, these pre-ESC conventions of various representatives are basically closed events that gets very little or (in my opinion) mostly no coverage in the mainstream media. If you ask me, these events are more or less for ESC fans and no one else. If you wanna exposure in media, you have to tour, but on this tour, you have to chose wisely where you will "advertise" yourself.
So, Daniel Luis, if you disagree with my line of argments, please, convince with (or at least try to find proof in form of) online articles by mainstream media that cover these events in headlines or at least on their main pages.
