Just days after the terrorist attack in San Bernardino, Calif. – the worst on U.S. soil since 9/11 – Trump sparked a media backlash for saying that all Muslims should be temporarily banned from entering the country.

The proposal has been ridiculed as impossible to implement and called racist by some, but it has resonated with many people concerned about the potential for terrorists to infiltrate the U.S.

Terrorism was the top concern of GOP voters polled in the CBS survey, followed closely by jobs and the economy and government spending.
