In all the talk about campaign finance reform, I haven' t heard anyone talk about the most sensible solution. We can forget about any credible way to limit campaign donations. The Clintons and Gores proved that. There are just too many ways to funnel money to candidates who are willing to break the law.
Buddhist nuns can make contributions that are reimbursed by the real donors.
Big businesses that want to influence a candidate can give bonuses to employees for the purpose of giving to a campaign. Lobbyists with deep pockets can think of a thousand ways to illegally put money into the campaign coffers. It would be impossible to close up all the loopholes. They don't need to monitor all the ways people and companies receive undocumented revenue. Might be something going on here.
