You'll have to do much more to convince me that Joe leveling a quid pro quo over a lawyer looking into his crackhead son's company, while he was in charge of watching over Ukraine, isn't ethically wrong. Especially as you argue Trump asking for something and not getting it was impeachable.
You have zero proof the man was corrupt except for allegations. Had Trump done this, you'd be howling... oh wait, he did far less and you howled anyway.
