Imagine zero political donations

Imagine an electoral system where no money can be given to any candidate. People who want to be elected will announce their ideas and personal qualifications in public place (the web). No campaigns. No ads.
Then, the social networks, without any outside money injected, will do their job: assessing the real value of people and ideas.
This “network intelligence” has its well known flaws: propensity to bubbles and bullying, empowerment of emotions and images. But these vices are already in the present system; and this network approach has the virtue of its resistance to manipulation.
In the end, we will be simply getting rid of the tendency money has to corrupt the political system.
