“We have to be careful. We’re allowing thousands of people to come into our country, thousands and thousands of people being placed all over the country that frankly nobody knows who they are. They don’t have documentation in many cases. In most cases. We don’t know what we’re doing. Let’s see what happens. This could be a very serious problem for the future,” -Trump.

Despite facing a substantial media backlash after he made the comments in December last year, polls taken immediately after the remarks showed that a majority of Americans supported a temporary ban on Muslim immigration.
How do voters feel about Trump’s proposal?

Fox News poll (Dec. 18, 2015 ) found 50 percent of voters favor Trump’s ban, while 46 percent are opposed.

However, when Trump’s name is removed from the question, support for the plan goes up five points and opposition goes down six: 55 percent favor the unnamed proposal, while 40 percent oppose it.

So while voters favor the “Trump” ban by a 4-point margin -- that increases to 15 points when the same ban is not associated with Trump.
