Reality is one if not both of them will be in government next time out, whether same as now without greens, or SF/FFI think they'll certainly last to 2023 but as we enter another winter of discontent major cracks will appear and rather than be blamed as the country edges towards the abyss they'll have a GE and then it'll be VERY interesting.
Not sure how you end up with a specific number of 33 for SF, and agree that the Greens will do poorly, but depending on how the election is run FF could go into power with SF.
I don't think people will trust FF and FG in the next government tbh. It will be extremely interesting to see if there'll be a pact between FF and FG for the next election. Because if there is, I think that's the end of them as separate parties for future elections after that. The political landscape will change into left of FF going to SF and right of FF going to FG
