A 15 seat loss is very much on the cards but nothing is certain until next year. Governments do tend to go through mid-term blues and added to this that FF will have been in office for 10 years come the next election there is an impetus for change.

Personally I wouldn't mind for FF to lose the next election so long as it isn't a landslide defeat. As a grassroots member its far more fun attacking than defending the government and it would be interesting to see how long the other crowd would be able to maintain a coalition with no common ideological thread except for a hatred of FF, however I would fear for the future prosperity of the country under such a situation
