The President can offer an Executive Order, but the groups that are watching – and scoring – the health care debacle on life issues are going to assume that such an offer is meaningless*.
You know what would be handy for the President right now? A reputation for doing what he said that he was going to do, come Hell, high water, or a recalcitrant Congress*. Shame that the President decided that such a thing was beneath his dignity, huh?
*You know. Like George W Bush had.
