A small group of wealthy individuals could exert massive amounts of political influence over a much larger group of less wealthy people.
I guess the smartcash team could limit the number of times an individual can vote during a specified time period. That wouldn't completely eliminate this nissue, but would at least minimize it to some extent.
To me the issue in my view is more about 1 SMART = 1 VOTE. I would like to see the community directly address the issue of the relationship between capital and political influence.
