Former Florida Governor, Jeb Bush, testifying before a House Budget Committee panel a couple days ago, championed the full transparency of all campaign donors.

Republic Report has the video:

BUSH: In a perfect world, we could have a different financing system. I love the idea of having campaigns be funded directly, rather than indirectly. And have no limits and total transparency so if people were offended by a large donor, the candidate, he or she, would have to accept responsibility for the message and the for the amount of money and who gave it. That would be, for me, talking about markets, rather than government control kind of response, that would be a better approach. […] I would suggest Congress should show more self-restraint about allowing that influence to change policy if that’s the view.
