From all the media coverage of the current U.S. presidential election, it seems that the "liberal" or "progressive" voice has once again entered U.S. politics. According to a recent Q&A at the Pew Forum, "the religious left" is more active. John Green, the Senior Fellow in Religion and American Politics, provides clear definitions of the religious right and religious left in the interview. He distinguishes "red-letter Christians" from "progressive centrists" and the "core religious left." Despite the subgroups in the body of people making up the religious left, John Green says that they are united by social welfare issues, environmental protection, and foreign policy. Other issues, such as abortion and same-sex marriage are "potential points of division." The religious left also has "in common a negative reaction to the religious right." Based on a 2004 Survey of Religion and Politics, the Senior Fellow estimated in the interview that the religious left totaled a little more than one-quarter of American adults.
