Lenin himself obviously had a lot of respect for the German party and seemed to have viewed it as already having a vanguard (before Kautsky's capitulation to imperialism) when he was writing his thesis in What Is To Be Done?:
"The reason lies in the fact that we failed to cope with our tasks. The masses of the workers proved to be more active than we. We lacked adequately trained revolutionary leaders and organisers possessed of a thorough knowledge of the mood prevailing among all the opposition strata and able to head the movement, to turn a spontaneous demonstration into a political one, broaden its political character, etc. Under such circumstances, our backwardness will inevitably be utilised by the more mobile and more energetic non-Social-Democratic revolutionaries, and the workers, however energetically and self-sacrificingly they may fight the police and the troops, however revolutionary their actions may be, will prove to be merely a force supporting those revolutionaries, the rearguard of bourgeois democracy, and not the Social-Democratic vanguard. Let us take, for example, the German Social-Democrats, whose weak aspects alone our Economists desire to emulate. Why is there not a single political event in Germany that does not add to the authority and prestige of Social-Democracy? Because Social-Democracy is always found to be in advance of all others in furnishing the most revolutionary appraisal of every given event and in championing every protest against tyranny. It does not lull itself with arguments that the economic struggle brings the workers to realise that they have no political rights and that the concrete conditions unavoidably impel the working-class movement on to the path of revolution. It intervenes in every sphere and in every question of social and political life; in the matter of Wilhelm’s refusal to endorse a bourgeois progressist as city mayor (our Economists have not yet managed to educate. the Germans to the understanding that such an act is, in fact, a compromise with liberalism!); in the matter of the law against “obscene” publications and pictures; in the matter of governmental influence on the election of professors, etc., etc. Everywhere the Social-Democrats are found in the forefront, rousing political discontent among all classes, rousing the sluggards, stimulating the laggards, and providing a wealth of material for the development of the political consciousness and the political activity of the proletariat. As a result, even the avowed enemies of socialism are filled with respect for this advanced political fighter, and not infrequently an important document from bourgeois, and even from bureaucratic and Court circles, makes its way by some miraculous means into the editorial office of Vorwarts."
