Carly Fiorina has filed her paperwork to set up a fundraising vehicle for a potential run at Democratic incumbent Barbara “don’t call me ma’am” Boxer:

SACRAMENTO — Former Hewlett-Packard CEO Carly Fiorina inched closer Tuesday toward a run for U.S. Senate next year, filing paperwork that will allow her to begin raising money for polling, political consultants and other preparations as she nears a formal decision in the next several weeks.
Fiorina, a Republican who served as a top surrogate to John McCain’s 2008 presidential campaign, has strongly signaled that she will challenge three-term Democratic Sen. Barbara Boxer in 2010. On Tuesday, she announced that she has filed forms with the IRS to create a political bank account, which she is calling “Carly for California.”
“I have received a great deal of encouragement to make a run for the Senate in 2010 from people across the political spectrum.”
