How are 50,000 people in New Hampshire going to change anything? That state has two representatives in the House of Representatives. What are two people in a corrupt legislature supposed to do?
One of the reasons that politicians can "get away" with the current campaign finance model is that on a national stage it almost never gets talked about and is never part of "the conversation". If something is important in New Hampshire, then it has to be part of "the conversation" at least once every 4 years.
