To run a petition campaign you need people and money, in the Mass FReeper world rather short commodidies. A petition needs about 80,00 signatures, plus support in the General Court, constitutional ammendment. The Cost judging from my experiences with the libertines is between $3 and $4 a signature, less with volunteers.
This does not include the election, I know of a lawyer in North Andover, that has drawn up a petition, interest and money lacking.
