I personally don't think people are ready to have Russia in the EU, although we surely all want to be close to Russia for different reasons (mine being cultural, and for all I know genetic, others' reasons may be energetic/political ...).

But the day that the EU will take in a member as populated as all the EU states put together, and as large as half the surface of the Moon, has not arrived yet.

I frankly think people are more open to Turkey joining (what's the EU average on this, has anyone seen the latest Euro barometer figures on this? is it usually at around 35% yes?). And ALL are certainly in favour of being best buddies with Russia.
