1.3 Congressional Committees Rule
There is simply too much work to be done in Congress for every issue to be debated by every member. That’s why a committee system was implemented to manage all the work. Once a bill is introduced, it is assigned to a committee and then a subcommittee, where it sits in limbo until the chair of the committees decide to work on it.
Your elected official might be enthusiastic about your issue, but without the support of the committee chair, the subcommittee chairs, and the leadership of the party in power, there is no hope for your issue to move forward.
