i wonder if senate elections are influenced by some factors or depends only by morale.
for example if i choose the war party and lose the last elections can i influence the elections in a way favourable to war party declaring war to another race; if a war is in a stalemate can it influence the rise of populists?if i build a lot of trade routes will it boost mercantile party strenght?summarizing rise of your opposition parties is random or depends from events and your way of play?
