这是GOP最大的基本盘了. http://www.businessweek.com/articles/2013-03-21/why-evangelical
Leaders of the largest evangelical churches came out this week in support of
granting citizenship to undocumented immigrants. The liberal approach is a
surprising shift for a group so closely affiliated with the most
conservative wing of the GOP, and the lobbying push that churches are
embarking on in tandem with their new position could have a big impact on
Republican leaders in Congress—most of whom are still uncomfortable
supporting citizenship because they see it as rewarding lawbreakers.
