Support for Donald Trump has slipped by 8 percentage points since Wednesday's second Republican presidential debate.

According to CNN, a CNN/ORC poll released on Sunday shows Trump still leads the crowded field of candidates, though he now garners just 24 percent of the vote compared to 32 percent prior to debate night.

Three days after more than 23 million people tuned in to watch the CNN-aired debate, the primary beneficiary of Trump's slip appears to be former Hewlett Packard CEO Carly Fiorina. She now places second overall at 15 percent, just a point ahead of retired neurosurgeon Ben Carson, who stands at 14 percent.

Just a month before, Fiorina had just 3 percent of the vote and pretty much seemed like an afterthought in the crowded field. That all changed on Wednesday, when 52 percent of all watchers identified her as the debate winner, compared to just 31 percent for Trump.

Fiorina's rise came just days after Trump seemingly ridiculed her over her appearance, prompting her to respond to his later attempts to downplay the issue by stating, "I think women all over this country heard very clearly what Mr. Trump said."

The poll of 1,006 Americans taken from Sept. 17 to 19, also found that Marco Rubio has now risen to fourth place with 11 percent of the vote, and Jeb Bush placed fifth at 9 percent.

On the issue of the economy, roughly 44 percent of voters thought Trump would best handle the country, well ahead of his closest competitors on the issue, with Fiorina at 11 percent, Rubio at 10 percent and Bush at 8 percent.

Trump also placed first on the question of who would best handle the issue of immigration, garnering 47 percent of the vote, compared to Rubio and Bush at 15 and 9 percent respectively.

Overall, 65 percent of GOP voters described themselves as either "extremely" or "very" enthusiastic about voting in the 2016 presidential race, compared with 51 percent of Democrats.
