As horrible as it sounds to defend as corrupt an individual as Trump, it is unfair to impeach Trump for something multiple democrats are themselves guilty of. At a Council on Foreign Relations conference in 2018, Joe Biden admitted to have threatened to withhold a billion-dollar loan to Ukraine until former Ukrainian President, Petro Poroshenko, fired a Ukrainian State Prosecutor who was investigating Joe Biden’s son, nearly the exact same corrupt act of political meddling that Trump now stands accused of. The State Prosecutor in question, Viktor Shokin, has since come forward and said that he had "been told to back off an investigation into the natural gas firm where Hunter Biden served on the board of directors" . But while this may not have broken any laws, it remains a clear conflict of interest, and the clear pattern of Hunter Biden's business dealings seem to clearly follow is father's life in politics, a further conflict of interest that strongly implies corruption.
But this corruption is not limited to the Biden family, there are a multitude of similar cases where democrats are accusing Trump of something that democrats are in fact themselves guilty of, for example the deep connections between Kremlin-funded interests with John Podesta and the Clintons. The Clintons in particular enjoy closer questionable ties to Russia than Trump, and have been implicated in aiding a Russian company, Rosatom, in "a campaign of bribery, extortion, money laundering and racketeering to gain control over U.S. nuclear assets in the private sector" . This case of corruption seems to have been known by the Obama administration who failed to do anything about it, implicating many democrats in corruption or complicity with it. Meanwhile Trump's approval rating has risen to the highest it has been all year amidst this impeachment inquiry, indicating public awareness of such blatant double standards is clearer to the public than democrats seem willing to believe.
