OK, so what exactly does the APPEARANCE of quid pro quo corruption look like? Y’know, as opposed to the real thing.

John Roberts wrote in yesterday’s opinion in McCutcheon v. FEC that Congress may still “regulate campaign contributions to protect against corruption or the appearance of corruption.”  He then limited “corruption” to an actual quid pro quo.

Which raises the question of what, exactly, the appearance of quid pro quo corruption looks like.  Y’know, as opposed to the real thing.
