Depends who bribed who most this year
It doesn't really work with bribes, it's purely a "I scratch your back if you scratch my back" thing.
If you look back over the last 20+ years, you will note:
a) Greece and Cyprus always exchange points at close to maximum
b) The northern countries stick together
c) The French usually have the better songs (performed in French, unlike all other contestants which often are barely able to speak English) but are shun by most other countries so they never win.
c) I have no idea why Italy returned. They have the San Remo festival where even the last-placed song is roughly 200% better than this Euroshit.
d) Since the Eastern Europe countries joined, points have been "distributed" between them which was a letdown for the "classical countries".
e) Average song quality has taken a nosedive since it was no longer required to sing in the national language.
f) Almost all the winners of the past 20 years are complete nobodies.
Most countries actually hope they DON'T win the competition. It is an _extremely_ cheap evening for tv production (you simply use the organiser's channel and a random dude that was punished by being chosen the commenter) unless you have to organise this crap contest. This is the ONLY reason many countries are still doing this crap.
