Answer:
Evangelical Protestants
Explanation:
Evangelical Protestants are considered the backbone of America's religious right. According to the Pew Research Center, this group of people tend to be of the White race, be of older age (baby boomers), and are made up of the middle-class in terms of wealth.

However, that isn't to say that Evangelical Protestants are all White. Sure, African-Americans, the elderly, and single mothers could very well be a part of EPs, but since it is asking most likely, then the choice of EPs is correct.
