I know what I THINK you mean. But this is most likely NOT Treason. Unless you think that voter fraud rises to the standard of 'levying war' against the United States. MAYBE Misprison of Treason -- IF foreign actors are actively engaged in the elections theft. More likely though, Rebellion/Insurrection, and/or Seditious Conspiracy, and/or Advocating Overthrow of Government.  Seditious bastards! https://uscode.house.gov/view.xhtml?path=%2Fprelim%40title18%2Fpart1%2Fchapter115&edition=prelim
