Just for Republican leaning voters:
Fundamentalist Baptist, Pentecostals - lower white economic class (Lintheads and small farmers) - the loosely connected to their churches will favor Trump, the more strongly connected likely with Cruz
Next rung - tons of Baptists, small Methodist churches, Pentecostals-Charismatics (think more Assembly of God types), non-denominational Evangelicals - 2000 s.f. homes and under - some college educated - some though lower numbers with Trump, lots for Cruz, some with Carson, some with Rubio, few with Kasich/Bush
Next rung - conservative town Baptist churches, larger non-denominational Evangelical churches, Confessional Presbyterians, Lutherans & Anglicans (some), more conservative-leaning but fairly small mainline churches - lots of college educated, lower level managerial folk, engineers, small business owners, etc. -- few for Trump, some for Cruz and Carson, lots for Rubio, good many for Kasich & Bush
Top rung - spire-town churches of various stripes, mainliners (PCUSA, UMC, ELCA, TEC, etc.), some Anglicans -- the wealthy of their communities, involved in social clubs, membership at the Country Club -- Trump gets the more racist of the bunch, few for Cruz or Carson, some for Rubio, Kasich and Bush's crowd
