Former Hewlett-Packard CEO Carly Fiorina says she'll run for the US Senate seat held by California incumbent Barbara Boxer. Fiorina ended months of speculation today with an announcement in an opinion piece she wrote for the Orange County Register. She's scheduled to make a formal announcement later in the day. The 55-year-old Fiorina was economic adviser to John McCain's failed presidential bid last year.
Before she challenges Boxer, Fiorina must win a Republican primary against a conservative state lawmaker who has worked feverishly over the past year to court GOP voters. She says her priorities would be creating jobs, cutting government spending and expanding access to health care—but not through a national health care system. If Fiorina dips into her personal millions to fund the campaign, "this could be the most expensive Boxer campaign yet," a spokeswoman says.
