Revise election laws related to school election deadlines

This bill updates Montana's school election laws by changing several key deadlines to align with local government election schedules. It directly affects school district trustees, candidates running for school board positions, and election administrators who manage these elections. The main changes include adjusting the timeframes for declaring candidacy, calling elections, and withdrawing from races to better synchronize with regular school election dates. For example, the deadline to declare intent as a write-in candidate for school trustee positions is now set 65 days before ballot certification, while the deadline to call a regular school election is set at 145 days before the election day. These revisions aim to provide more consistent timelines across different types of elections in the state.
