How can they listen to the voters if the voters never speak to them. My comment was not on the DNC or RNC but on the core of all forms of representative democracies.
Do you know the name of the member of your state’s House of Representatives that represents your district? When was the last time you spoke to your federal representative? Do he/she not answer your calls because they have to many constituents? Talk to people in your neighborhood about the need for more representatives in the house.
All sovereign power comes from the people. Read: you are that guy.
Re-read my comment above. They only have power which we vest in them.
