After the Constitution is amended to enable campaign finance controls, laws need to be written and passed to implement these controls, starting at the national level. Currently 0.2% of Americans provide 2/3 of the total amount of money spent by national candidates and political parties, and 98% give zero. This obviously gives a very small minority of wealthy donors and special interest groups a big advantage in deciding what laws are enacted.
One possible solution is to have the elections publicly financed. Each voter could have $50 of public funds to allocate to candidates he or she likes.
Another possible action that could be taken would be to mandate that all contributions to candidates and political parties be publicly disclosed, as well as candidates’ tax returns.
