On The Posner Show, Sarah and Grant discuss Catholics and the election. Why did the vice-presidential candidates get asked about their Catholicism only in terms of their views on abortion? They discuss the reasons the Obama campaign has scaled back religious outreach. Is there really such a thing as the Catholic vote, anyway? Sarah asks Grant about the "On All of Our Shoulders" letter, a critique by Catholic theologians of Paul Ryan's economic policy. Does Catholic doctrine support the conservative conception of smaller government? Grant sheds light on an effort by a Republican political operative to claim that the Obama campaign is calling voters with an anti-Mormon message. Plus: Lightning round on the baseball postseason.
