The new survey finds that 34 percent of adults would favor establishing Christianity as the official state religion in their own state, while 47 percent would oppose doing so. Thirty-two percent said that they would favor a constitutional amendment making Christianity the official religion of the United States, with 52 percent saying they were opposed.

Although a large percentage of Americans said they would favor establishing a state religion, only 11 percent said they thought the U.S. Constitution allowed states to do so. Fifty-eight percent said they didn't think it was constitutional, and 31 percent said they were not sure.

The U.S. Supreme Court has ruled that the First Amendment, which (among other things) prohibits the government from establishing an official religion, also applies to the states.

Republicans were more likely than Democrats or independents to say that they would favor establishing Christianity as an official state religion, with 55 percent favoring it in their own state and 46 percent favoring a national constitutional amendment.
