Obama's presidency would have to be declared illegitimate by a court of law [Supreme Court] before it could be declared null and void. Even though he lied about who he was, he was legally elected President in 2008.
Biden's presidency is a fabricated one. At most he is president of a bankrupt defunct US Corporation. Biden is being played by an actor wearing a silicone mask.
The real Senator Biden was found guilty of treason and other high crimes and executed in 2019. I believe this date is correct.

We have all learned now that the Supreme Court is the most corrupted Judicial Court within the United States of America

He was select, voting both times, my vote was changed to vote for odumbo, I caught it and yelled out, the lady said I'll change it back, I told my husband check his vote, it changed to odumbo, I turn and told the whole building...I'm like how can they change it " ' I told people while walking out, it spread fast.
