Keeping the spirits clean?
She's out doing politics. Fine. She drags in prayer. I don't like that, but I'm used to the political appropriation of religion in America. But what is this notion of "keeping the spirits clean"? The "spirits... around us"? Does she think we all have spirits around us, spirits that can be unclean?
What religion is that? Is she dabbling in... New Age? Is she a witch?
Now, she does pause and chuckle/scoff between the words "keeping" and "spirits," and that might suggest an ironic distance from the common folk who believe in such things. Or — listen and judge — it might mean that she's aware that it's a bit daring to let it slip that she believes we are surrounded by clean and unclean spirits that influence our fate.
