Read this, from WaPo:
Some numbers and trends that jump out most:
* Catholic voters broke 53 to 45 percent for the GOP, a reversal from 2008, when they supported the Democrats by a 55 to 42 percent margin.
* White Catholics in particular supported the GOP 58 percent to 40 percent; two years ago, they backed the GOP by a narrower 52 to 46 percent margin.
*Republicans also gained the support of 59 percent of Protestants, up six points from 2008 and five points from 2006.
* Republicans also gain more support from white evangelical Protestants. Seventy-seven percent backed the GOP, up from 70 percent in 2008 and 2006. (White born-agains have tended to be more GOP in presidential elections.)
What I see in Putnam and Caldwell, a book we are reading, is the increasing connection of politics and faith.
