Problem

Fractal's election analytics team is reviewing state-level participation totals. Write a PostgreSQL query to identify the state or states that recorded the highest number of votes.

Requirements

  1. Join states to state_votes using state_id.
  2. Calculate the total votes for every state, treating states without valid vote records as having zero votes.
  3. Return all states tied for the highest total, with columns named state_name and total_votes.
  4. Sort tied results alphabetically by state name.
