Giuliani 27% (meaning his support falls in the range of 31% to 23%)
Romney 16% (support in the range of 20% to 12%)
McCain 13% (support in the range of 9% - 17%)
Huckabee & Thompson 11% (support in the range of 15% to 7%)
So in essence, there is a statistical tie for second place among all the candidates listed except Rudy.
Thank you for your reasonable explanation and response. Because of the criticism I received I looked up the whole "statistical tie" thing in the context of the margin of error in a poll. I found article after article, and explanations from mathmeticians, that say that the statistical tie term is misused more often (especially by the press) than not when referring to political polls. In fact, and I didn't save a link, I found one mathmetician's explanation that disagrees with yours. But I found others that would agree with what you said.
