I suspect that unfortunately Hillary's switch to angry partisan will actually help her. She couches it in terms of being willing to fight for the voter's interests, while implying that Obama will not. One of the talking heads over the weekend (I heard it on the radio) was counseling her to do exactly that--to change from an appeal to the voter to support her to a pledge that she would be a fighter on behalf of the voter. Voters like fighters--fighting for them.

And Hillary can do this very effectively since voters also like simple answers--"universal health care--no exceptions" or "freeze on interest rates". Many will not stop to examine these slogans--Hillary's health care mandate means you must buy it even if you don't want it. And the freeze on interest rates may well make it hard to get mortgages.

She believes in the KISS principle--and it works.
