Generally speaking, I don't think POTUS should have pardon power.
I think pardoning Hunter is a bit hypocritical, but since the incoming administration is swearing revenge and the R's have had a hardon for HB for a while now, I don't really fault him for trying to protect his son. I also can't find an ounce of giveadamn about his gun charge.
Was weirdly silent around here when Trump went on a pardon spree at the end of his term, though.
