@phillmv @Rickperlstein in US politics, i think Bernie Sanders is an exemplar here. on the one hand, he never overtly threatened, after shitlibs moved heaven and earth to defeat him, to quit the party and take his voters with him. on the other hand, he and Biden negotiated a settlement, under which Biden became in domestic economic matters the best US president since LBJ. the threat of defection was always present in those negotiations, but i suspect tacitly rather than wielded as a cudgel./fin
