Sadly name calling is counterproductive and often inaccurate.  People called G.W. Bush unintelligent also.  The two have much in common but lack of brains is not one of them.  Neither one chose to use their brains to study and learn the lessons of history or the depth of certain issues.   In the case of the current president, he can't be bothered and is easily bored by climbing up his steep learning curve.  And when he and his family claim their incompetence is because they came late to politics, I have two comments for them:  First, if you weren't willing to study the art of governing, why claim to be chosen as the most competent administration in years (especially during the campaign) and second, what kind of citizen/voter were you before the campaign?  The average non politician citizen is supposed to know a few things:  there are three co-equal branches of government, Abraham Lincoln was a Republican, etc.
