I don't mean to suggest that at all -- I think there are a variety of things we could try to mitigate some of the problems associated with campaign finance.
What I'm trying to communicate is mostly that when it comes to "buying influence", the problem is a lot deeper than any access/influence purchased via donor-driven fundraising. It's actually inherent in any arrangement where money can be used to hire people to lobby on an employer's behalf. And it's particularly unbalanced when most people don't lobby on a volunteer basis.
