I like this summary by Brian Flemming:
The Democrats won a mandate without excessive God-talk and without actually winning over evangelicals in significant numbers. The election results weaken the argument for religious pandering; they don’t strengthen it.
This is not to say that we can tell the religious to just go away, but that what we should do in politics and government is continue to push purely secular values, and trust the sensible evangelicals to find common cause with what is right…just as I will vote for evangelicals who can promote progressive values in spite of their silly supernatural beliefs.
