Matt Yglesias of Vox is excited by a new Gallup poll that produced this headline:

Charlie noted that this is a little odd because it’s not really clear why the Left would want to claim moral approval of extramarital affairs, human cloning, and polygamy as a core social value (approval for all of them has risen). But it’s also worth noting there is a social issue you can very easily think of where Americans are not moving left, and may in fact be moving right — abortion, which happens to be of a more important ethical issue, by most lights, than anything else on Gallup’s list.

Michael New has exhaustively documented these positive trends for NRO over the years; I’m not sure if Yglesias thinks the tick up from 42 to 45 percent of Americans considering abortion moral is significant, but it’s not, especially in light of the other evidence on the issue. This isn’t an original insight, but it is worth reemphasizing, since there may be tactical lessons from the abortion battle that has gone so much better than others have, and worth celebrating, given the unmatchable importance of abortion among “social issues.”
