Umm, James, to cut through all of this: should he sign socially conservative bills or not? Or will he veto socially liberal bills, such as expansions of taxpayer-funded embryonic stem-cell research, that may pass a Democratic Congress? Giuliani doesn’t need to solve the problem of the limits of politics in shaping a moral order — he merely needs to answer these questions.
As for your reference to what Bush hasn’t done, I am not sure what you are talking about. Do you mean his lack of proactive social conservatism? I don’t think anyone expects Giuliani to be more socially conservative than Bush. But they do want some idea as to how he will deal with social issues. Not philosophically but in his constitutional capacity as one who signs or vetoes bills.
