Fiorina made her announcement at Earth Friendly Products in Garden Grove, Calif., where she discussed her top priorities including job creation, economic recovery and restoring fiscal accountability in Washington. "Throughout my career I've brought people together and solved problems and that is what I plan to do in government - set aside ego and partisanship and work to develop solutions to our problems," she said in a statement.

"I believe big change is not impossible, but it does require leadership, innovative thinking, teamwork and tackling the most obvious and pressing problems first," Fiorina said. "My campaign is going to be about solutions that work for the people of California and about holding Barbara Boxer accountable for her failed record over her last 18 years in the Senate, her utter failure to lead and her track record of bitter and ineffective partisanship."

She will face off in the GOP primary against California Assemblyman Chuck DeVore. For more information visit CarlyforCalifornia.com.
