Haven't done the analysis for Ukraine yet but if you want the Russia E/W no lose to cover your other selection(s) then you should get the 4's needed in running round about the San Marino vote at position 9 (quickly before Latvia at position 10 give 12 or 10 to Russia/Ukraine in whatever order taking them up the board again.
Failing that another good stalling point where the price may wander out to 4's is just after the French vote at 17
edited to say having looked through the vote schedule around 17 after French vote is a good point to look for a covering Ukraine bet too - prob get ~5's, 6's
Good luck
