Who the actual forget cares like how is influencing public opinion considered rigging an election? Like really who cares if some Russian dudes spammed social media or whatever. Voters are individual people who have minds and opinions. If they want to seek out their own validation for who they want to vote for let them holy stuff.
Unless Russia was physically interfering with polls through actual hacking and espionage or other illegal activities like modifying poll counts, this entire allegation is loving pointless and not even worth the thought or effort to carry out and the fact that even the department of Justice is dedicating resources to this stuff is absurd
