Last year when I saw Trumps game of criminalizing Biden by focusing on his son I became extremely disinterested in buying into those dirty tactics.
Trump was pointing out the proven fact of the Biden family having engaged in financial scams, which included Influence Peddling, Russian Money Laundering. and having taken over a Billion from the CCP. (Now, of course, we know Joe Biden took millions from both CCP and Russian Lobbyists during the last election.)
All of this was not President Trump's fault but the fault of the Biden family who engaged in all of this. The fact that they did so was relevant since Biden was running for President.
'Dirty tactics'? Hardly - Trump was bringing Biden family crimes to light, which - again - was relevant to the election.
Trump was not the only one who brought up Biden family crime. For instance, during Pelosi's 1st failed Impeachment scam, members of the State Department testified under oath how Joe Biden had committed Perjury by claiming he had no idea what his son was doing and how he had never met with Burisma members. They told how they advised Biden NOT to meet with Burisma employees who showed up in DC asking to meet with Biden while using Hunter's name as leverage, to avoid the appearance of a Conflict f interest but that Biden had ignored themand met with the Burisma reps anyway. They said in testimony that the Bidens should be on the stand under oath.
So don;t blame Trump for pointing out facts others were also divulging...and don't blame Trump for the Bidens' crimes.
