Perhaps independent voters can devote their financial resources to electing people, not political parties.  Much of the financial support that Trump/Sanders receive come from individuals outside the traditional party structure.  Does this reflect the desire of independents to elect candidates seen as not tied to the traditional party system (even though both are running for office under the party banner)?  I also wonder if there were others, like me, who voted for Walker because he did NOT belong (officially) to either party?  

I'm guessing there is a pent-up demand by independents to elect someone outside the current two-party system.  No, not someone far left or far right ... but someone seen as being outside the traditional two-parties.  Whatever "independent" means, I think more people are looking for leadership beyond D's and R's.  I say let the "outsiders" have a chance.  It could change peoples' perception of government.
