If Trump would have lost as expected then the "Trump-Russia" BS would've been dropped.
The Democrats tested 2 things - Trump-Russia and Trump-sexual assault and saw that no one cared about Trump and Russia so they went with the sexual assault/Access Hollywood tape route. Why did no one care about Russia? Funnily enough, for the same reason Obama said in 2012 - the Cold War has been over for 25 years.
Trump was NOT being investigated for Russian ties, that's why it was never mentioned. It was only until he won that this BS started.
The funniest thing about wailing about James Comey is that Comey was nominated to his former position by a Democrat president and confirmed by a Democrat senate.
Of course, the term October surprise has a lengthy history dating back to the 1980 elections or even before. Smart and successful campaigns know about that and prepare for it. Then again, the loser of the 2016 election was too stupid and too lazy to campaign in the right states, so the proof is in the pudding.
