Poll: Cain 28, Perry 18, Romney 17, Paul 11

This poll was conducted after Perry’s most recent subpar debate performance last Thursday, but the survey was still in the field when Cain won a Florida straw poll on Sunday. Cain was the top choice of only 8% a month ago.

Michele Bachmann continues her drop in our polling, falling from a first-place 34% on June 30 to just 4% now. While some other announced GOP candidates have had large fluctuations in their standing with party voters, since June 21 Romney has remained steadily between 12% and 17%.
