Politico: “After a 30-minute meeting between Jim Barnett, Brown’s campaign manager, and Warren campaign manager Mindy Myers, Warren’s campaign issued a statement saying, “the proposal [Brown] has put forward still includes loopholes that Karl Rove could drive a tank through….Under the proposal floated by the Republican senator, if an outside group were to advertise on behalf of either candidate on TV, radio or the Internet, the one who benefits would be forced to make a charitable donation of a sum that is equivalent to half of that ad buy. The idea is to discourage outside groups from spending heavily in the state since doing so would essentially impose a financial penalty on the candidate they are trying to help.”
