Iowa Republicans appreciate retired neurosurgeon Ben Carson’s more controversial comments, according to a Bloomberg Politics/Des Moines Register poll released on Friday. The poll found Carson leading Trump by nine points among likely Iowa Republican caucusgoers.

According to the survey of likely Iowa Republican caucusgoers, 81 percent approved of Carson’s comment that Obamacare is the “worst thing that’s happened in this nation since slavery;” 77 percent said they liked his statement that Hitler’s rise could have been stopped if German citizens had had guns; and 73 percent liked his concerns about a Muslim becoming president.

Among the respondents, 96 percent said they find Carson’s “common sense” attractive, and 89 percent said they like that he is guided by his faith, according to the poll. Only 32 percent of those surveyed believe Trump is a committed Christian.

The new Bloomberg/Des Moines Register was the second poll released this week showing Carson overtaking Trump in Iowa.

Bloomberg/Des Moines Register surveyed 401 likely Republican Iowa caucusgoers via phone Oct. 16-19 with a margin of error plus or minus 4.9 percentage points.
