ed, there may have been some marketing effort, but I bet it didn’t take a lot to associate the "Gipper" nickname to ol’ Ronny. People naturally have a tendency to associate people with their accomplishments, and even though we know Reagan was merely acting the part, we still associate him with the character.
I’m sure that happens anywhere famous actors bridge the public/private spheres.
What I find more interesting is that, in this case, Reagan was not really a "famous actor". He was more famous for his political activities and life than for the movies he made, in my view. However, he seems to have been able to carry the image with him, defying logic (as it were).
