Do you have anything to back that up? Or is this just you making stuff up?
From the article, “Cain garnered 25 percent support of Republican primary voters in the poll released Tuesday, compared to Romney's 21 percent

You are correct. The poll results with Cain having 25% percent are only from Republican primary voters. At the link they list out a little more info about sub-groups, but not everything.
