Abolish the Electoral College.  Presidents should be elected directly by the people, thus this institution is inherently undemocratic and gives smaller states a disproportionate advantage when selecting a president.  The Electoral College also makes possible situations in which the popular majority of the votes went to one candidate while the Electoral College majority went to another candidate, thus overturning the will of the majority of the citizen voters (as has happened in 1824, 1876, 1888 and 2000).
