“All parties without exception recognize us as a political power, and exactly in proportion to our power. Even the craziest reactionary that denies us the right of existence courts our favor and by his acts gives the lie to his words. From the fact that our assistance is sought by other parties, some of our comrades draw the strange conclusion that we should reverse the party tactics, and in place of the old policy of the class struggle against all other parties, substitute the commercial polities of log rolling, wire pulling and compromise. Such persons forget the power which makes our alliance sought for, even by our bitterest enemies, would have had absolutely no existence were it not for the old class struggle tactics. If Marx, Engels and Lassalle had accepted from Bernstein and his modest or not modest fellow thinkers the tactics of compromise and dependence upon bourgeois parties, then there never would have been any Social Democracy; we would have been simply the tail of the Progressive party.”
