At the Politico, Ben Smith reports that in several states – Virginia, Wisconsin, Colorado, and Iowa – Obama is running radio ads criticizing McCain for his stance on abortion rights. Noam Scheiber, after commenting on how unusual this is, notes that it’s probably a good move on Obama’s part, since a majority of Americans support abortion rights in one form or another, and pro-choice Republican women are likely to be turned off by McCain/Palin’s strongly pro-life views. Like Scheiber, I’m a little surprised to see Obama running explicitly on his abortion stance – normally Democrats are either compromising or capitulating – but I’m glad to see it happening. The steady erosion of reproductive rights over the past twenty or so years has happened in part because Democrats have been unwilling to make the positive case for reproductive rights. Granted, this ad campaign is somewhat limited, but it is still very heartening to see a Democrat run towards, and not way from, the party’s stance on abortion.
