There has been much discussion about whether votes in this next election will be counted securely.
Every state has rules about what poll observers can do at the polls and how votes can be challenged. Here are the rules for your state:
Connecticut Each registrar may appoint one or more challengers in his town or district, one of whom may be present at the offering of any vote. (Conn. Gen. Stat. § 9-232)
Each registrar may appoint one or more challengers in his town or district, one of whom may be present at the offering of any vote; and any such challenger or any elector may challenge the right of any person offering to vote, on the ground of want of identity with the person on whose name the vote is offered, or disfranchisement or lack of bona fide residence, and the moderator shall decide upon the right of the person so challenged to vote. (Conn. Gen. Stat. § 9-232)
