I did not take the question to mean anything about manipulation. If that is the case it would change my answer. If you look at the meanings of these two words, i think you see that there is a difference. Influence has a positive connotation and manipulation a negative one. I believe manipulation to have a self-seeking motive that uses affect on others' behavior to one's own personal benefit and others' detriment. Influence, however, i take to be motivated by desire to share potentially helpful facts and opinions.
Manipulation is the conscious, intentional short-circuiting of others' emotions to affect a desired outcome. The difference is the audience probably would not be persuaded if all the facts were presented transparently. Note that facts and even logical argument can be a part of this (in an attempt to appear reasonable and objective). Rhetoric and B.S. are pretty much synonyms for this.
