Your post illustrates that you don't understand any of this.
Hillary was not complaining about voter fraud in 2016. Instead, she complained about Russian interference in the election.
Every election has some amount of fraud and glitches, but not enough to impact the result.
But you claim that the 2020 election was stolen, although you offer no proof.
I do have proof of attempted fraud in 2020 - Trump tried to convince the Georgia Secretary of State to find 11,000 votes for him.
