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:
Kansas Each person who is authorized to appoint poll agents may appoint one per polling place. Each person appointed to be an authorized poll agent shall be a registered Kansas voter; a member of any candidate's immediate family; or be a person under 18 years of age but at least 14 years of age who meets all other requirements for qualification of an elector except that of age (Kan. Stat. Ann. § 25-3005a; Kansas Secretary of State).
It shall be the duty of each judge of election to challenge any person offering to vote, whom the judge shall know or suspect not to be qualified as an elector. (Kan. Stat. Ann. § 25-414).
At most points in the electoral process, interested individuals and groups may observe the proceedings at the precinct polling sites, at the county election office, or at the county or state canvass. The principal means recognized in state law for public observation of electoral proceedings is the authorized poll agent. Poll agents are commonly referred to as poll watchers. Each of the following persons is automatically a poll agent because of the position they hold: state or county party chair; chair of a committee formed to support or oppose a question submitted election; candidate; political party precinct committee man or woman; write‐in candidate for statewide office who has filed an affidavit of write‐in candidacy with the Secretary of State. A person may be appointed to be a poll agent by one of the persons listed above. Election observers—In some cases political organizations, including international groups and foreign groups, will request permission from the county election officer or the Secretary of State to observe the voting process in a county or counties. The Secretary of State or county election officer may grant permission on a case-by-case basis, reminding all such groups that they must follow all laws and all policies established by the election officer.
