Larry Sabato gets it right:
Let’s suppose Mrs. Clinton wins in November 2008. Democrats would have to live with the consequences. There is simply no question that Senator Clinton would be the third deeply polarizing President in a row, following her husband’s divisive and partially wasted tenure and George W. Bush’s deeply disappointing turn at bat. We bet that she would have a short honeymoon and would be unable to convince her millions of critics and detractors that she had changed – or was different than they long ago concluded she was. At a time when the nation could use a unifier and a healer – to the extent that any President can perform those roles – partisan warfare would be at fever pitch from Day One.
