He tripled his support in one month while Perry tanked 10 points. Clearly, Herman Cain is benefiting from Perry missteps and lackluster debate performances.
Meanwhile, Mit Romney's support is unchanged and Michele Bachman is on life support.
The new poll found Cain's support has nearly tripled among GOP primary voters to 17 percent.
That's up from 6 percent before this month's debates, and puts him in what is essentially a three-way tie with Perry and Romney.
After three September debates, Herman Cain is in the top tier, Rick Perry has stumbled and Mitt Romney's holding steady.
Cain has benefited not only from his debate performances, but also significant media attention after winning the Florida Republican Party's straw poll on Saturday.
Perry now garners 19 percent, a drop of 10 percentage points from a month ago. That puts Romney back in the top spot with the support of 23 percent. Last month Romney was at 22 percent.
Newt Gingrich recovered some ground and now stands at 11 percent. Ron Paul receives the backing of 6 percent now compared to 8 percent before the September debates.
Bachmann registers 3 percent support, down from 8 percent in late August and a high of 15 percent in July.
Romney surged ahead of Perry in a Florida poll as well.
What Cain does with this new found attention will determine his staying power. The charismatic business executive will be put under the microscope, which always creates adversity for a candidate. How he handles the pressure will show whether he is truly the "Anti-Romney candidate" conservatives are looking for.
