Carly Fiorina, the next California senator?

Good thing former Hewlett-Packard Co. (HPQ) CEO Carly Fiorina is running to be California's next U.S. senator. She wouldn't stand a chance at getting elected queen of Wall Street.

Fiorina, once considered one of the most powerful women in business, has heard the siren call of public service. Last week, the Republican filed paperwork with the IRS that will allow her to begin raising money for what likely will be one of most expensive senate races ever -- if not the most expensive. A spokeswoman for Fiorina declined to comment.
