It does seem there have been some people running for national office with a lack of understanding of certain things you figure a President should either know or know how to bluff around.
However, there is a lot of "gotcha" or "gaffe" mentality in the rival media. If the President says something factually off, its a major gaffe on FOX and if a GOP candidate says something that could be interpreted as not knowing what he should, it's a big deal on MSNBC.
However, after sorting through the "gotcha" moments in journalism, it is still clear the public has a right to expect a certain conversancy in history and world affairs from those seeking the Presidency.
But its also true that many recent Presidents have not had direct foreign policy experience, including the last two.
It's true a good manager, a good listener and a person with temperment and judgment are what is needed for office, whether its the Presidency or a local office. Voters will decide that, although for the Oval Office a good 85% will just be voting for party and won't care if their candidate didn't know China has nukes or if America has 57 states.
