The sudden srop in Trump's support has been linked to his critical comments in the aftermath of the Nov. 13 Paris attacks. The attacks left hundreds wounded and 130 people dead.

Trump latest contentious comment comes his recent controversial statement concerning Muslims residing in America. The presidential aspirant suggested that he would keep mosques under surveillance to root out domestic terrorist plots.

Trump told a NBC News reporter that he would support requiring all Muslims within the United States to be registered to a special database, which his critics have likened to the mandatory registration of Jews in Nazi Germany.

Trump recently mocked handicapped New York Times reporter Serge Kovaleski. Critics are on him for flailing his arms and distorting his speech while apparently mimicking Kovaleski.

According to Yahoo News, Trump mocked the reporter as he defended the latter's assertion that during the Sept. 11, 2001 attacks, he watched on television as "thousands and thousands" of people in New Jersey cheered while the World Trade Center fell.

Trump is not the only front-runner to drop in the latest survey. Retired neurosurgeon Ben Carson has seen his poll numbers drift downward with just 15 percent of Republicans who partook in the survey saying that they would vote for him. Carson now trails Trump by more than half. As recently as late October, Carson trailed Trump by only six points.

Texas Senator Ted Cruz and Florida Senator Marco Rubio follows Carson and are tied for third place, with at least 8 percent each.

The average sample size of the five-day rolling poll ranged from 464 to 347 respondents. It was conducted between Nov. 22 and Nov. 27, with a credibility interval of 5.2 to 6.1 percentage points.
