If meaningful change in national elections is to come, it must come from the people via some intiative action.  Members of Congress, with very few exceptions, are so entrenched in the two-party system and so dependent on their campaign donors that they will never support change which might threaten the status quo.  Preferential voting would significantly empower third party and independent candidates and public funding of campaigns with the removal of PAC dollars would completely change the landscape of campaigns.  Congress will never adopt either....it's up to the public to work AROUND the vested interests and make those changes.  As this editorial notes,  without some significant changes, things will only get worse.
