Seems former Arkansas Gov. Mike Huckabee is working to not be “left behind.” He’s gained the support of both authors of the popular “Left Behind” apocalyptic series. His campaign announced Monday that he received the outright endorsement of series co-author Jerry Jenkins, the first time Jenkins has endorsed a candidate. And The New York Times reported Tuesday that Tim LaHaye, the other co-author, wrote a letter with his wife, Beverly, that was distributed to conservative Christian pastors to encourage them to attend conferences in Iowa, New Hampshire and South Carolina. The former Arkansas governor is the only candidate scheduled to speak at them, the newspaper says.
