In general, the recent wave of pardons in the last month reflect the trend over the last 20 years of pardons by both parties being increasingly political, self-interested and granted to connected donors who mount targeted campaigns. Sadly, it's not a great look. Yet I believe the pardon process can, and should, serve an important function of being a final check and balance to correct prosecutorial and judicial excess when it occurs. I'd be happier if the majority of pardons were commutations of grossly excessive sentences in cases most people have never heard of.
Hopefully, many of the more unusual and controversial recent pardons were a final paroxysm in response to the increases in politically-related prosecutions or threats of such prosecutions by partisans on both sides. Regardless of the validity (or lack thereof) of these prosecutions (or threats), it's clear many were pursued more aggressively, timed or conducted with at least one eye on either influencing political optics or retribution. Overall, it's certainly not been a shining moment for our republic. Both parties share the blame and need to do better.
