If any tax records are outed and are problematic for Trump, the records that will be outed on Obama and his Ukraine, China and other deals will be fierce and ready to go. And for his crooked son, his crooked sister, and his crooked brother.
The earlier days of everyone assuming that Trump was involved in lots of shady business deals because he was a businessman but someone like Joe was above it all because he was just a simple government paycheck hack are longggggggggggggggg over. Trumps bragging about net worth and dubious business deals are baked into the process already and he was voted in with that assumption. Same with his shady dealings/interactions with women.
This is all new for Joe though. It started with the hunter and burisma thing. Mr. Nice Guy goes to Washington with the Nice Guy family ended out having his scumbag family and corrupt dealings exposed. And now Biden is taking it on the sexual assault charges. So you can go after Trump more, but Joe will be the one to pay the price. Joe is sitting on some big bucks since he left office and he sold out America to get much of it.
All the lefties in congress and in the media are hot to get Trump for firing the IG for the State Department, alleging that he was on Pompeo's arse or something. Heh, this is the guy who covered up and would not go near Biden's interference in the Ukraine and Hunter's involvment even though state department employees had complained to the inspector general. Go for it. You will probably get in some hits against Trump, but it will blow a couple of Biden's appendages off as collateral damage. Works for me. The bloodier the better.
Hope you like the sight of blood flowing because Joe is going to continue to get cut up badly and it has not even started yet.
