Is there a non-derogatory synonym for “propaganda”?

Is there a non-derogatory synonym for propaganda?

Specifically, I’m talking about a word to describe the sum of all messages a particular political member has broadcast (through various media), but one without the negative connotation of “brainwashing” that propaganda can carry.

Solution 1:

Generally, when referring to a candidate's or party's collective set of opinions and messages, the word platform can be used.

Barack Obama's platform resounded with the voting populace to a greater degree than that of Mitt Romney.

Solution 2:

Narrative usually refers to the recent history of messages flying around in some society on a given topic, usually with the faint implication that this history ignores, oversimplifies, or otherwise diverges from the objective truth of a situation. But it can also be used to describe one person's involvement: "Mr. X's speech furthered the popular narrative on Y."

I personally don't like the word much; it's one of a number of words that a certain breed of academics like to use when clutching their pearls. But it might be what you need.
