Allows election challengers to be present any time ballots are being cast

HB 1802 repeals and replaces Missouri election laws to allow political party representatives to designate election challengers who can observe voting and ballot counting. Specifically, party chairs may appoint registered voters in the jurisdiction as challengers for polling places (during all voting hours) and absentee ballot counting locations (during absentee voting and counting periods). Challengers must be verified as eligible by election authorities before the election, and may only raise concerns about potential election law violations to election judges or authorities. This bill directly affects political parties' ability to monitor election processes at polling sites and counting locations.
