They have no evidence Hunter did anything illegal other than the drugs, gun, etc. The evidence they took at the hearings resulted in the witness getting convicted for lying. What did Hunter do? Who did he bribe? What was done to get the bribe? It is all wild speculation. And there was nothing Joe did. Having the prosecutor fired was the policy of the U. S. and European powers because he was corrupt (and not investigating Burisma).He's guilty... He knew exactly what hunter was doing and i'm sure they discussed it many times... It would be impossible for him not to know and not be involved.
People want to believe Biden did something wrong because of the partisan split we have today. If they believe Presdent Trump was tortured in a police station with Secret Service protection they will believe anything Trump says. And, so far they have.
