BOSTON (AP)- The government watchdog group Common Cause Massachusetts is calling on U.S. Senate candidates Gabriel Gomez and Edward Markey to agree on a plan to limit the influence of outside spending in the campaign.
The group said a similar "People's Pledge" between Democrat Elizabeth Warren and Republican Scott Brown in last year's U.S. Senate race greatly reduced the amount of undisclosed cash spent on the campaign and the number of negative ads that would otherwise have been seen.
Common Cause released a report on Thursday that showed spending on outside groups totaled only 9 percent in the Warren-Brown race, compared with an average of 34 percent in three other competitive races studied in Virginia, Wisconsin and Ohio.
Gomez, a Republican, has rejected a call by Democrat Markey to sign a pledge limiting outside spending.
