Right. What does the word "influence" mean to you? Take your time. 
I mean, I'm currently watching a series on Auschwitz and there's been a fair amount of discussion about how Hitler's propaganda - lies - about the Jews and other ethnic groups was directed at the German population to get them to believe that Jews were inferior beings, contaminating the planet, taking jobs and other resources from the Germans, etc. 
It's accepted that all that hate propaganda definitely influenced the German people and their allies against the Jews, to the point of demonizing them and painting them as worthless animals. 
Let me get this straight: You don't believe such a campaign against Clinton could have ubfluebced people to vote against her? Correct?
