Republican presidential frontrunner Donald Trump’s recent proposal to ban all Muslims from entering the U.S. has far from hurt his poll numbers; in fact, a poll released Wednesday found that almost two-thirds of GOP primary voters back the widely-condemned plan.

In a new Bloomberg Politics/Purple Strategies poll, 37 percent of all likely general election voters said they support Trump’s plan while 65 percent of likely Republican primary voters said they back the ban.

Support for the controversial proposal remained nearly unchanged after those surveyed were presented with more information about the plan, including the statement “it will make our country less safe by alienating the allies we need to fight ISIS.”

“We believe these numbers are made up of some people who are truly expressing religious bigotry and others who are fearful about terrorism and are willing to do anything they think might make us safer,” Doug Usher, leader of Purple Strategies’ research arm, said of the results.

Trump’s anti-Muslim plan makes 18 percent of all general election voters more likely to vote for the real estate mogul, Bloomberg reported. Thirty-three percent of voters said they were less likely to back Trump after the plan, while 44 percent reported the proposal has no impact on their vote.

The national overnight poll of 605 likely 2016 voters was conducted online Dec. 8 using an opt-in representative panel. It has a 4 percent margin of error.
