If an incumbant took no money for re-election, the influence of lobbyists would be related only to their ideas and the worth of those ideas to the country.  We should replace campaign contributions with public money for incumbants in an amount equal to private money for the incumbant's opposition.  We provide a completely even playing field.  We provide freedom for individuals to participate in opposition to elected officials and we free elected officials to do their job without constantly being on the hustle.
