There's a new outsider in the Republican in crowd.
Following a strong performance in Thursday's Republican presidential debate, former Hewlett-Packard CEO Carly Fiorina has vaulted into second place in the race. Fiorina's support in a new CNN/ORC national poll of registered voters now stands at 15 percent, up from the 3 percent she received when the poll was last taken in early September.
Billionaire Donald Trump still leads the GOP field, yet the 24 percent support he now registers is 8 points lower than the 32 percent he received earlier in the month. Ben Carson, the third candidate in the race to have never held elected office, also saw his numbers drop. Carson received 14 percent in the poll, down from the 19 percent he received in the previous CNN/ORC national poll.
But Fiorina was not the only candidate with reason to celebrate. Florida Senator Marco Rubio also experienced a bump from the second Republican debate. In the early September survey, Rubio had received just 3 percent support. In Sunday's version he showed 11 percent, putting him in 4th place behind the trio of outsiders.
The news was not nearly as encouraging for Wisconsin Governor Scott Walker, an early conservative favorite, who is now polling at less than 1 percent. That downward trajectory began after Walker received 10 percent support in CNN/ORC's July poll. In mid August, he received 8 percent support, and in early September he had fallen to 5 percent.
The CNN/ORC poll was conducted Sept. 17-19. It surveyed 1,006 American adults, including 924 registered voters, of whom 444 are Republicans and independents who lean Republican. The margin of error is plus or minus 4.5 percentage points.
CORRECTION: An earlier version of this story incorrectly stated the level of Fiorina's support in the latest CNN/ORC poll.
