Capitalism v. Socialism

What this report tells me is that few Americans seem to know the difference between the two. A telling passage from the article:

The question posed by Rasmussen Reports did not define either capitalism or socialism. It is interesting to compare the new results to an earlier survey in which 70% of Americans prefer a free-market economy. The fact that a "free-market economy” attracts substantially more support than “capitalism” may suggest some skepticism about whether capitalism in the United States today
relies on free markets.

This suggests that while Americans support what capitalism is, they don't support the term for it.
