As a quick exercise in semantics, I really do think it is helpful to separate evangelicals from fundamentalists. While both are theologically conservative, only the latter is truly literal in its Biblical interpretation. (Many -- most? --evangelicals believe in evolution, for instance, while no true fundamentalist would.) The terms are grey and ever shifting, but it's really not fair to either camp to lump them all in a huge sectarian tent.

Among fundamentalists -- and I would count the students of Patrick Henry in this number -- there is little nuance in religio-political beliefs. But evangelicals are not so monolithic, and I even suspect the beginnings of a liberal (political) revolution may be in play. Though my study sample is obviously skewed, I participate in a region-wide forum of evangelical grad students of all denominational flavors, and within this group I have met everything from conservative Republicans to die-hard Democrats and even -- shock upon shock! -- a couple of quasi-socialists. This demographic is still largely Republican, of course, and I don't think that's going to change rapidly...but a backlash to the past decade of American politics seems to be afoot.

Now as to the two-spheres approach that I have adopted, I think that's far less common. Just as those conservative Christians have pegged their politics to their faith, the liberal ones seem to be following suit. Sometimes I think they are fearful to do otherwise.
