In her sincere embrace of her family and her nonjudgmental introduction of her pregnant daughter, Palin won the hearts of many single moms. By evoking life in a modest, middle-class town, she established an empathy with voters akin to what Bill Clinton built when he ate at McDonalds'.
How are the Democrats to live down their assaults on Sarah? How not to seem the enemies of the very voters they have to get?
Strategically, Palin achieved the convention's core goal - to show how McCain is not a clone of George Bush, but a man of the people eager for change and demanding of reforms.
Now the gap between Obama and McCain is not so wide. Now it is clear that they both stand for change.
So now the fear of a naive and untried Obama leading the nation through perilous times at home and abroad can work to drive voters over the narrower synapse and get them to vote for McCain.
Mission accomplished, Sarah.
