If "the American people" sent Democrats, or Republicans, or the President, or somebody else "a message" in the mid-terms, it is this:
"Hi. We can't tell our asses from a hole in the ground."
As it happens, we already knew that. But thanks, American people, for sharing.
As for "getting it," I find it interesting that presumably the President doesn't get "it," and Nancy Pelosi doesn't get "it," but apparently Republicans who deny the reality of anthropogenic climate change, who think deregulating for-profit enterprise will lead to better behavior, who think tax cuts unto infinity will cause spontaneous libertopian paradises to spring up from the ground, who think there is no separation between church and state, and who believe that Obama is a socialist do get "it."
Maybe "it" is The Stupid?
Maybe it would be better if we didn't "get it"? Otherwise, we're all very likely to get it in the end.
The next two years look to be very, very bad, indeed.
