Progress for Washington, the Super PAC funded entirely by Laura Ruderman's mother, reported spending another $37,864 on postage and printing today, bringing its total reported expenditures to $277,126.

Today's report included two expenditures reported as "supporting" Ruderman. A previous mailer allegedly supporting Ruderman included attacks on Darcy Burner and Suzan DelBene, but I'm told that yesterday's supporting mailer included entirely positive messages.

Too bad for Laura, because negative advertising works.
