You want more God with your politics -- how about this?
There are a lot of good reasons to not want politicians waving God around. I have heard young evangelical Christians sing happily that "my God is greater than your God," confident they are praising their Lord. In fact they are setting up the prerequisite for the oppression of the wrong-believers and the unbelievers.
But a politics that does not spring from some kind of moral vision -- some kind of generous moral vision -- is just narrow self-interest projected on society. The magic of the market, the extraordinary abundance we enjoy thanks to invention and competition, can blind us to the necessity to extend community to all and to bind ourselves together. That's what a democratic polity does when it is working. It's hard, but the alternatives are horrifying.
I am already curious what the First Lady might do when she finds her feet in a post-presidency. Not until after four more years, of course. But freed from the need to measure every word, what will Michelle do?
