Consumer advocate and Harvard Professor Elizabeth Warren, fresh from her stint helping set up the Consumer Finance Protection Bureau, will officially announce her campaign for the U.S. Senate against Scott Brown tomorrow.

The exact schedule is still being worked out, but Warren seems intent on learning from the mistakes of Martha Coakley, who lost to Brown in 2010 and was much maligned for not wanting to shake hands in the cold in front of Fenway Park.

Granted, it will be 84 degrees in Boston tomorrow, but Warren will kick her campaign off by greeting commuters in Boston in the morning, then traveling to New Bedford, Framingham, Worcester, Springfield, according to an aide.

Here’s a written statement from Warren today: “The pressures on middle class families are worse than ever, but it is the big corporations that get their way in Washington,” said Warren, who in recent weeks has been in kitchens and living rooms listening to people all across the state. “I want to change that.  I will work my heart out to earn the trust of the people of Massachusetts.”
