This little campaign incident underscores two huge problems:
First, Senator Clinton is not an experienced campaigner. It's true that Mrs. Clinton campaigned with Pres. Clinton in the past. It is very different to be the candidate's wife than to be the candidate.
Second, Mrs. Clinton cannot separate herself from her husband. In simple terms, she is Bill's wife and that's it.
My advice to Senator Clinton: Sit out for a few more years and develop a legislative record. Then run for president as an accomplished senator rather than Bill's wife.
P.S. Also, many liberals do not think that Senator Clinton can win! See DAMNING DEM DOUBTS ON HILLARY By DICK MORRIS and EILEEN McGANN.
