You're describing Donald Trump. Donald Trump has lied about everything he's every done, because he's FAILED at everything he's every done, except conning people and defrauding them of all of their money. He's really ******* good at lying, grifting and conning people. The Greatest Conman Who Ever Lived.
While Trump was failing at everything he tried, despite being born with every advantage in life, Biden was overcoming every obstacle a man could have thrown in his path in order to succeed, and doing it all without the advantages of wealth and privilege that Trump's wealthy father provided for him.
Trump has been a loser all of his life, blowing everybody else's money, while never having to pay anyone back for his failures. That's why American bank's won't loan to him. That's why he's been convicted of fraud - pretending he's smart and wealthy, when he's not.
Biden has made the most of every opportunity he's been given, to rise from a working class background to become the most powerful man on the planet.
Trump has ZERO accomplishments he can openly brag about. Being a rapist, a fraud artist, and a liar aren't anything that people admire, so he has to pretend to be rich, successful, and that everybody loves him, because not even his family is out campaigning for his innocence or his re-election.
