Attached is a sample Congressional Debate bill. I will break down the different parts of the bill to help you write your own.
Short Title: This is where you state the intent of your bill. This should not be longer than 3 lines. It is a short description of what your bill will do.
"Whereas" clauses: This section is for explaining the motivation of your bill. Here you will address WHY this bill should be passed. Why do we need it?
"Resolved" sections: This is where you state exactly what the bill will do. Make sure to include who will implement it, where any necessary funding will come from, and when the bill will go into effect.
IMPORTANT: Make sure the bill only takes up one page! Of course, in real life Congress legislation can take up multiple pages, but for the purposes of competition, one page is sufficient.
