Marx wrote about this exact phenomenon over a century and a half ago. Insane how nothing changes.

They do not need to weigh their own resources too critically. They have merely to give the signal and the people, with all its inexhaustible resources, will fall upon the oppressors. Now if in the performance their interests prove to be uninteresting and their potency impotence, then either the fault lies with pernicious sophists, who split the indivisible people into different hostile camps, or the army was too brutalized and blinded to comprehend that the pure aims of democracy are the best thing for it, or the whole thing has been wrecked by a detail in its execution, or else an unforeseen accident has this time spoiled the game. In any case, the democrat comes out of the most disgraceful defeat just as immaculate as he was innocent when he went into it, with the newly won conviction that he is bound to win, not that he himself and his party have to give up the old standpoint, but, on the contrary, that conditions have to ripen to suit him.
