Hmmmmm. Let's think about this. Not only has Joe not issued a preemptive pardon, he has not stepped in to prevent the DoJ from indicting his kid. On charges, it has been pointed out, that are rarely prosecuted. Especially with respect to the tax charges since his back taxes have been paid.

So arguably, a two-tiered system of justice is being applied to Hunter resulting in him being treated unfairly. Yet Joe is letting the process play out. Even though, according to his conservative accusers, Joe runs the risk of having corrupt financial transactions getting exposed while Hunter's tax issues are being investigated.
This is all happening to a private citizen who never had a position in the government. It doesn't take much imagination to guess what Trump's social media feed would look like if this was happening to Donnie J or Queen Ivanka.
