Saying that she has learned in recent years that "decisions made by the Senate impact every family and every business, of any size, in America," former Hewlett-Packard CEO Carly Fiorina used an op-ed in The Orange County Register to announce today that she's running as a Republican against Democratic Sen. Barbara Boxer of California in next year's election.

As the Los Angeles Times notes Fiorina will first face a primary against state Assemblyman Chuck DeVore.

During last year's presidential race, Fiorina was an economic adviser to Republican nominee Sen. John McCain.

Fiorina lost her job at Hewlett-Packard in the wake of its troubled merger with Compaq.
