Former Hewlett-Packard CEO Carly Fiorina declared her intentions to run for Senate in California in a Wednesday morning op-ed in the Orange County Register. Fiorina, who has been exploring a campaign against Democratic Sen. Barbara Boxer for months, is expected to announce her candidacy in person at an Orange County, Calif. event at 1 p.m.

In her op-ed, Fiorina wrote that she has “not always been engaged in the electoral process,” but, through her business career, began to understand the impact of government. “I now understand, in a very real way, that the decisions made by the Senate impact every family and every business, of any size, in America,” she wrote.

Fiorina said her top priorities in the Senate will be “economic recovery and fiscal accountability.” She then went on to stake out her opposition to Democrats’ proposed health care insurance overhaul. But, in an echo of the Barack Obama, who won California with 61 percent of the vote in the 2008 presidential race, Fiorina concluded, “I believe big change is not impossible, but it does require leadership, innovative thinking, teamwork and tackling the most obvious and pressing problems first.”
