Requires notice be provided upon changes to voter registration; prohibits changes in party affiliation from being processed after statutory deadline.

This bill prevents county election officials from updating a voter's political party affiliation after the deadline for primary elections (55 days before the primary). It requires officials to notify voters within five business days if they submit a party change after the deadline, explaining that the change isn't processed, they remain affiliated with their previous party, and they can vote in that party's primary. Voters denied voting in their preferred primary due to registration errors can cast a provisional ballot and seek court review; if a court confirms they were lawfully affiliated with the desired party before the deadline, the ballot is counted. The bill directly affects voters seeking to change party affiliation after the deadline and county election officials managing voter registrations.
