The President, the spearhead of the Nation, is a representation of Us, and therefore Our morals. I don't think the President is responsible of solving moral dilemmas, and to think that s/he can is ridiculous, because they will undoubtly exist and even multiply as our advancements in science and our encroachment into uncharted territories continues.

It is not the 'job' of the President to solve moral issues, but in the end it does end up being so. That's why is is so important who we intrust such power to. That's why, so many times, religion and beliefs do become an issue when deciding on who represents us. Morals are fundamental in determining law, that's why so many are concerned with electing a President with 'their' morals, which can inturn be construed as 'their' religious belief.
