Populist Reform of the Democratic Party

So if MONEY is part of a SYSTEMIC problem
in what way can that be addressed?
I seems to require politicians with enough spine
to risk not getting BIG donations from traditional sources.
Does such a political creature exist?

To overhaul the electoral system means those
in Congress would be putting PUBLIC needs before their own.
A rare bird indeed!
Perhaps Populists have a role in naming names and shaming
those who sellout the Public for personal gain?

It may be easier to push electoral reform
than getting money out of politics?
Then with enough support in Congress,
work to solve the money issue?
If for no other reason than the right-wing fringe also
has a distaste for self-serving, career politicians.
This is an area where unexpected allies presents itself?
