I suspect Trump would have offered Hunter a pardon. But Joe didn’t want just a pardon for the tax and gun convictions. He needed a BLANKET pardon to make sure Hunter wouldn’t face charges for bribery, money laundering and influence peddling in China, Kazakhstan, Russia and Ukraine. Such charges could bring down the entire Biden organization.
IIRC PDJT previously said he would pardon Hunter.
But your assessment is prolly correct. Why issue a pardon for crimes not charged, and for a specific time period?
CYA!!!
