promise-2
Explanation
A politician stands at a podium and declares: "If elected president, I promise you I will do whatever my opponent promises to do, plus 1." The caption below reads: "There is an optimal election strategy, but nobody has the nerve to execute on it."
The joke is rooted in game theory and auction theory. In a competitive election, if you could simply promise to match your opponent's platform and then add one more thing, you would logically always win -- you are strictly better by definition. This is similar to the concept of an "n+1" strategy or a one-upmanship equilibrium. The humor comes from the fact that while this is theoretically optimal, it is obviously absurd in practice: it is transparently cynical, reveals you have no actual convictions, and reduces political competition to a pure bidding war. The caption's observation that "nobody has the nerve" is ironic, since the reason nobody does this is not cowardice but rather that it would expose the emptiness of campaign promises in a way voters would find insulting. It also satirizes how political campaigns already functionally operate this way, just with more rhetorical window dressing.
