Trump's proposal to temporarily ban Muslims from entering the US is opposed by a solid majority of Americans, while almost four in 10 Republican primary voters support the idea, a new Wall Street Journal/NBC News poll has found.
Those views within the party have helped Trump weather yet another political storm, as the poll found his favorability rating undiminished among Republican primary voters over the last six weeks.
Among Republican primary voters, 39 per cent opposed and 38 per cent supported the idea, which has been the subject of heated debate since Trump called for a "total and complete shutdown" of Muslims' entry into the country.
The poll also found that nearly 60 per cent of Americans have a favourable view of Muslims, a larger share than in polling conducted several months after the September 11, 2001, terror attacks by Islamic extremists.
The survey was taken after violent attacks by Islamist militants in Paris, the shooting massacre by a radicalised Pakistani woman and a Pakistani-American husband in San Bernardino, California, and other places raised public concern about terrorism.
President Barack Obama has urged Americans not to respond by viewing all Muslims as a dangerous force, but Trump has called for a pause of Muslim immigration "until our country's representatives can figure out what is going on."
Despite wide criticism, including from most of his presidential rivals, the debate over Trump's proposal has not substantially changed his standing with the public.
Among Republican primary voters, 51 per cent saw Trump in a positive light and 26 per cent negatively, nearly unchanged from late October.
