I'm sure the Russians would've preferred for Mrs. Bill Clinton to win, after all, she is known to be grossly negligent with tens of thousands of emails including some that were secret and even top-secret.
On the other hand, you could look at this and think that Putin knows our press as well as anybody but Rush Limbaugh. For a measly one million dollars he placed some ads on the longshot that Trump would win knowing the left would cause trouble for a long time with their claims of "collusion". He knew the left couldn't handle the truth that Mrs. Bill Clinton was such a terrible candidate that she would lose to Donald Trump. Putin's meager investment hit the jackpot.
That is a good point about the divisiveness and obstructionism brought about by President Trump’s election; I hadn’t considered that.
