I wouldn't object to candidates being required to provide a list of donors from whom they've accepted donations

Is this not already the case (at least as far as corporate donations are concerned)?

I have no problem at all with individuals making donations, or at least I know that it is undoubtedly, constitutionally right. I can't help but think though, that collectives getting involved in funding campaigns is a problem.

I have a way to go before I understand the process well enough to effectively articulate my reasoning. The reason I commented in your thread here is because you almost invariably speak with great clarity and logic. On this though, I can't help but think that there is a greater ideal than simple transparency.
