GERB - to please and reassure their electorate that Borisov is still a factor and the victories are not meaningless;
BSP - to show that even at the lowest point in their history, they remain "responsible statesmen", realizing that others are more successful in the role of a strident opposition, and now they have a vital need for legitimacy and currently this is participation in power;
ITN - to refute the image imposed on them of superficial brawlers who sabotage any government, even that with their participation and even the possibility of their own;
APS of Dogan - to show that they are "the good DPS", ready for dialogue in the name of statehood, terrified by the prospect of being together on one side of the barricade with Peevski, who deceived them;
Vazrazhdane: Because they will continue to be in their favorite aggregate state of opposition, which, even if it has not brought them any serious added value lately, does not cause them any damage. While participation in power will certainly harm them electorally. Their fans want them "bad" and irreconcilable and they will remain that way, without having to change on the move;
PP-DB: Because they need to look around and listen in peace, outside their zone of frank discomfort in government. A wonderful opportunity to slightly shake off the stigma of "incompetents and ajamies" and to tighten their ranks - if not organizationally, we do not see such efforts in places, then at least on a mental level among their supporters;
DPS - Novo nachlas: Because the lack of a mathematical and image chance, at least for now, to participate in management gives the hyperactive Peevski the opportunity to implement whatever he has in mind for the next match, without suffering public anger because of management decisions;
MECH - the same as "Vazrazhdane", just on a smaller scale;
