On some of the above television talk shows it was mentioned that Obama knew about the Russian interference in our presidential election as early ss last August. The question is why did Obama not come forward about the Russian interference? No one had a good answer but here is my opinion.
Obama was caught between a rock and a hard place. If he announced Russian interference in August Trump and Republicans in general would cry fowl and accuse him of trying to give an additional edge to Trump. Further, at that time most polls were showing Clinton having a substantial lead. Therefore he chose not to muddy the election and let it take its course. In the end Trump won in a close race surprising most of the experts.
I remember at the time being surprised at just how big of a lead Clinton had. Now I wonder if somehow Russia was able to rig the polls anticipating that the President would draw the conclusion that he finally reached not to disclose Russian interference.
Russia must somehow be punished and I certainly don't know how to do this. In an earlier time what Russia did would be considered an act of war. Today with Nuclear weapons cooler heads have prevailed.
