"especially : a declaration of principles and policies adopted by a political party or a candidate" (emphasis my own)
Meanwhile, in 2020, Trump is sending in federal agents to abduct citizens in to cars, presiding over the world's worst pandemic response, and lining the pockets of billionaires while doing it. Fucking beauty.
The first definition is
PLAN alone. Therefore you are incorrect. The definition is plan, can be used to mean plan, and is the primary definition.
The second definition is "a declaration of the principles on which a group of persons stand". You are incorrect again, even on this definition. In the commentary or guidance of the second definition it says "especially : a declaration of principles and policies adopted by a political party or a candidate". That is not the definition, however, and is commentary/guidance on how it is usually used. The second definition is "a declaration of the principles on which a group of persons stand". It can involve "policies," and this is often involved, but is not the definition.
So we see multiple issues on the understanding of a simple word, on what it means and how it can be used. You must resort to an interpretation of a commentary to a secondary definition, reading that it says that policies are often involved, and declaring to us that it must always involve policies, rather than relying on the definitions themselves.
