Vice President? Most definitely.
President? Well, I hope she would get more experience first. Being Vice President would give her that experience.
Breaking a tie vote in the Senate?
Being ready to be President if the President becomes unable to serve?
Hardly the experience I am looking for.
Being a very popular executive of a State and a town Mayor are much more applicable.
Being a community organizer and running a succesful primary campaign.... not so much.
