We really need to put limits on the pardon power. It's clearly enabling corruption. Ford should never have pardoned Nixon. It's been a slide down the slippery slope ever since.
Both of the recent presidents have made some very questionable pardons.
In this case we elected a President who categorically said he's pardon people who engaged in criminal behavior for him. The voters expressed a preference for corruption, and trying to fix that after the fact won't help. A democratic country that wants corruption will have it.
