The City of Newton sent out a summary of the charter question on the ballot to all households. You should have received it or will receive it shortly.
The first portion is the summary of the charter change as it will appear on the ballot. This was authored by the charter commission. They declined to include a sentence mentioning the elimination of ward-elected councilors from city government.
The 2nd section is an objective summary of the charter changes authored by the city law department.
Finally the 3rd and 4th sections lay out the case for and against the charter authored by the Yes and No ballot committees.
The summary is available online at the bottom of the elections page on the City website.
