"1976 was the first year Gallup asked Americans if they had been "born again," as Hackett wrote in a 2008 paper. The organization's measurement methods varied over the next decade, but in 1986, the organization first asked the "born-again or evangelical" question that it uses today. Over that time, self-proclaimed born-again Christians and evangelicals helped reshape the political landscape. In 1976, the born-again former Georgia Gov. Jimmy Carter was elected to the White House. After that, political interest in evangelicals and born-again Christians remained, but Rev. Pat Robertson's 1988 second-place finish in the Iowa caucuses in particular made it clear that white evangelicals were swinging Republican. Outspoken Christians like George W. Bush continued the trend of winning over these conservative Christians, and targeting those voters is still a key campaign strategy for politicians like Mike Huckabee and Rick Santorum."
