Peter Dorman makes a good point, but that is not the half of it.
The reality is that as long as there is no direct quid pro quo like money under the table there is no conflict of interest, lest alone corruption or the commission of a crime. This is the principle behind the revolving door between government and the private sector, as well as the related ways of rewarding politicians for promoting special interests.
Even Bill Clint's "renting out" the Lincoln bedroom to big donors was A-OK as long as there was no specific understanding explicitly entered into.
All this looks like a broad and deep conspiracy against the public and the public interest in the name of "capital formation" and "job creation."
