Bill (and Hillary) Clinton didn’t have a record of touting “abstinence education”. Nor was Reagan holding himself out as a standard-bearer for conservative-religious family structure — he was divorced and not apologetic about it.
Neither has that been Palin’s platform. Those are issues she stood for, but those are not platforms she ran on. If you watched some of the archived debates CSPAN has been showing, she ran on economic conservatism, the State taking control of its resources (wrestling them away from environmental groups), and fighting political corruption.
Family values issues are outside the Constitutional scope of a President’s responsibility. The President’s primary role, according to the Constitution, is to be Commander in Chief of the US Armed Forces, secondary roles are to appoint judges, ambassadors and cabinet positions, negotiate treaties, and report to Congress and the nation the state of the nation.
One standpoints on issues you brought up are only tetratrary matters that will be guideposts as to the kind of judges that person may appoint or how they will enact bills they are given to sign.
Let’s be careful about demanding our President be Pope. Moving away from Constitutional roles is the reason why we have all the messes we do.
