District residents will not have a chance to decide whether to ban corporate contributions in local politics after regulators said the initiative’s supporters didn’t collect enough signatures to secure a place on the November ballot. The activists, though, said they are considering an appeal.

The D.C. Board of Elections and Ethics ruled Wednesday that the D.C. Committee to Restore Public Trust had fallen 1,726 signatures short of the 23,298 to put Initiative 70 before voters. The proposal would have barred donations by corporations to campaigns, transition and inauguration committees, legal defense groups and programs that handle constituent requests.
