Obama was informed one year before the election that Russia was meddling. But he chose not to do anything about it because Hillary was a lock and he didn’t want to do anything to distract from her presidency.
Both sides of the isle have confirmed that Russia meddled in our elections. There is absolutely something there.
The question is, did the Trump campaign knowingly or unwittingly collude with them. If there were something, it would have been leaked by now.
If the Russians were responsible for the Podesta email leak, it still doesn’t prove that there was collusion. However if it is confirmed that Seth gave the documents to Wiki-Leaks, It really is the end of the story. The media won’t completely give up, but it takes most of the wind out of their sails.
