The cause of the failure lay mainly in the awkward alliance between a politically incapable general and a street-demagogue, capable but recklessly violent, and filled with passion rather than with the aims of a statesman.

They had agreed excellently, so long as the question related only to plans.

But when the plans came to be executed, it was very soon apparent that the celebrated general was in politics utterly incapable; that his ambition was that of the farmer who would cope with and, if possible, surpass the aristocrats in titles, and not that of the statesman who desires to govern because he feels within him the power to do so; that every enterprise, which was based on his personal standing as a politician, must necessarily even under the most favourable circumstances be ruined by himself.
Opposition of the Whole Aristocracy He knew neither the art of gaining his antagonists, nor that of keeping his own party in subjection.

The opposition against him and his comrades was even of itself sufficiently considerable; for not only did the government party belong to it in a body, but also a great part of the burgesses, who guarded with jealous eyes their exclusive privileges against the Italians; and by the course which things took the whole class of the wealthy was also driven over to the government.

Saturninus and Glaucia were from the first masters and servants of the proletariate and therefore not at all on a good footing with the moneyed aristocracy, which had no objection now and then to keep the senate in check by means of the rabble, but had no liking for street-riots and violent outrages.
As early as the first tribunate of Saturninus his armed bands had their skirmishes with the equites; the vehement opposition which his election as tribune for 654 encountered shows clearly how small was the party favourable to him.
