Background (unrelated to question, but it is what lead me to ask the question)
My SO and I were talking about an alternative solution to how Senators are elected other than through direct popular vote. She brought up the idea of a mini-electoral college per state, as opposed to appointment by state legislature (which is what it was before the 17th amendment). Moreover, she posited that the drafting body for each State's Electoral College could be impaneled like a jury. I was intrigued by this proposal and wanted to send something to my reps about this idea. However, I am unsure about how exactly to do this at the federal level. This lead me to ask...
If I have an idea for Federal bill, how exactly do I send this idea to my Federal Representatives?
