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:
Maryland The following persons or entities have the right to designate a registered voter as a challenger or a watcher at each place of registration and election: the State Board for any polling place in the State; a local board for any polling place located in the county of the local board; a candidate; a political party; any other group of voters supporting or opposing a candidate, principle, or proposition on the ballot. An election judge shall permit an individual other than an accredited challenger or watcher who desires to challenge the right to vote of any other individual to enter the polling place for that purpose. A majority of the election judges may limit the number of nonaccredited challengers and watchers allowed in the polling place at any one time for the purpose of challenging the right of an individual to vote. A nonaccredited challenger or watcher shall leave the polling place as soon as a majority of the election judges decides the right to vote of the individual challenged by the challenger or watcher. (Md. Ann. Code Art. 33, § 10-311).
An election judge shall allow the following individuals to have access to the voting room at a polling place: a voter; an individual who accompanies a voter in need of assistance in accordance with § 10- 310(c) of this subtitle; polling place staff; a member or other representative of the State Board or local board; an accredited watcher or challenger; an individual under the age of 18 who accompanies a voter; and any other individual authorized by the State Board or local board. (Md. Ann. Code Art. 33, § 10-308 for information on individuals authorized to be in the polling place).
An election judge shall permit an individual other than an accredited challenger or watcher who desires to challenge the right to vote of any other individual to enter the polling place for that purpose. (Md. Ann. Code Art. 33, § 10-311). The right of an individual to vote may be challenged at the polls only on the grounds of identity. (Md. Ann. Code Art. 33, § 10-312).
