to be long-term competitive the republicans need to try gaining black evangelicals and brown catholics and generally trying to get the nonwhite vote
remember, most nonwhites are quite socially conservative
Black evangelicals don't vote like white evangelicals; they are either urban or they are rural poor. Hispanic Catholics heavily vote their economic interests because they are urban or suburban -- which means that they vote heavily Democratic this time. Mexican-Americans tend to be very conservative on law and order issues -- but law and order itself draws them into the Big Government interests.
The GOP absolutely must redefine itself if it is not to find itself shrinking a little more every year. The white Evangelical/Fundamentalist segment of the population has peaked. Rural America is not going to grow faster than non-rural America.
