It's down for Donald Trump and up for Ben Carson as new national poll shows the retired neurosurgeon is now on the first place by a small lead.

The latest survey was conducted by New York Times and CBS News between Oct. 21 and 25 and involved a random sample of 1,289 individuals. The poll results were released last Tuesday.

According to the results, 26 percent of GOP primary voters are in favor of Carson and 22 percent of the support goes to Trump, which gives the retired neurosurgeon a lead of only four percentage points.

Although the difference is just small, this is the first time that Trump was displaced from his consistent position since polls were conducted in July.

The Boston Globe noted that no other candidates closely follow the two Republican contenders. The others behind them only have single digit scores.

Florida Senator Marco Rubio garnered eight percent; former Florida governor Jeb Bush and Carly Fiorina tied at seven percent.

Senator Rand Paul, Senator Ted Cruz, Ohio governor John R. Kasich, and former Arkansas governor Mike Huckabee each had four percent support.

Although Carson now takes the lead, it doesn't speak much about the final results and changes can still come.

According to CBS, seven out of 10 GOP voters say that it's too early to tell if they've made up their mind about their candidate.

In addition, majority of Trump's backers are more certain about their choice compared to Carson's supporters.

More than 50 percent of Trump supporters say they've made up their mind about their contender, while only 19 percent of Carson's backers are sure about their choice.

Also, the survey found that over 40 percent of the respondents believe that Trump has more chances of winning the election, as opposed to only 21 percent who think that Carson would dominate in November 2016.
