They want to come back into the SPL, obviously. In order to do that they need a majority (not sure exactly what it is) to vote them back in. It seems like they would get the required votes, although I don't think the rest of Scottish football fans are happy about that. Apparently there are plans to boycott games if they are allowed back in.
I guess it will all boil down to money at end of the day and if the rest of the SPL clubs decide they would make more with Rangers being in the PL, then that's what will happen. When money is involved, morality goes out of the window. They should be busted down to Division 3 - simple as that.
