You are saying that the dollar amount spent decides every election. Do you really believe that democracy is nothing more than rule by whoever spends the most money?
Not entirely but is has a very big impact, are you saying that money spent in an election doesn't have an impact? We don't even know the true dollars spent anymore...
Follow up, do you want MORE foreign funds deciding elections for your nation over what citizens and national companies contribute?
This isn't just for elections either, this is for legislation after election... I don't believe anyone would want foreign money deciding their leaders, best interests and laws.
