Tsk.
You think details matter, Yaelle?
I posed this exact question to some people some weeks ago. To a man, they said it wasn’t about the actual votes.
ANYONE is allowed to influence the electorate. The President of Whogivesafukistan can make a speech telling Americans whom to vote for. Movie stars can EVEN threaten to LEAVE HOLLYWOOD if you don’t vote their way. All legal.
Unless Putin changed the voting machines or votes, or ability to register, or registered every Russian to vote here, this cannot be blamed on Russia.
