This article talks about a judge's decision that affects how the Postal Service can handle mail-in voting rules that were suggested by a leader. Imagine the judge as someone who decides the rules for a game. The leader wanted to make new rules, but the judge says they need to wait before playing by these new rules. People are trying to figure out if these new rules are good or not, kind of like when you decide if you want chocolate or vanilla ice cream. Some people are worried about how mail-in voting will work, which is like sending a letter to choose your favorite superhero.
