(CNN) -- If Barack Obama is re-elected on November 6, he will owe more to his first lady than any president ever to win a second term.
On Tuesday night in Charlotte, North Carolina, Michelle Obama gave one of the finest speeches ever delivered at a national political convention. More important, it could have more impact on the immediate future of the country than her husband's celebrated 2004 keynote address to the Democratic National Convention in Boston. Why?
Her speech tied the Obamas' personal stories directly to the lives of millions of voters struggling not to be the first generation of Americans unable to offer hope of greater opportunities to their children than they had, thus drawing a contrast with Mitt Romney as an unnamed but unmistakable caricature of privilege without shading her talk with negativity or animosity.
