Two themes emerging from the DNC is that Hillary Clinton is a "change-maker" and "the most qualified" person to ever seek the Presidency.
She has decades of exposure to public policy, and can make an argument she has a grasp of world affairs and has many contacts. She can also make an argument of having more tempered judgment.
However, what is there to suggest Secretary Clinton offers any prospect for the change voters yearned for this year ? And as far as being the most qualified person ever ? Washington, Jackson, FDR, Ike, Reagan....Hard to say. Forty three Presidents before Obama, and all are a reflection of their times and had different skill sets.
