(Combined Sources) The Massachusetts Republican Party is calling on volunteers to serve as poll watchers in the upcoming election. “With one of the most important elections of our lives on the line, the Massachusetts Republican Party is leaving nothing to chance,” party Chairman Jim Lyons said in an email Friday. He said integrity at the ballot box begins and ends with attentive citizens and “poll watchers are necessary to minimize any risk of fraud.” State law allows a political party to appoint a person to act as a challenger of voters at polling locations as long as they are not disorderly and do not obstruct the access of voters.
