Is it true that Russia had something to do with trump winning the presidency ?

No, they didn’t hack the election.
There were crazy stories about both candidates which appeared on Facebook and other outlet feeds. Don’t you know? This is what the fake news was all about.

Trump should have lost once that “pvssy grabbing” thing came out. Hillary barely won her US Senator seat in 2000, and she only won that by dumb luck because Rudy dropped out of that race. Then she lost to Obama in 2008 and she was close to losing to Bernie in 2016. Hillary may have had a lot it of votes in California, but otherwise she is a weak candidate. If it wasn’t for the media and Hollywood pulling so hard for her, she would have lost by a lot more votes.

No. We have alot of security protecting voting frauds.

Putin controls the Electoral College which alone has any real political power in the US. It's easier to bribe, threaten and extort, let alone corrupt a small group than an entire nation. Though a majority of millions voted for Hillary Clinton the popular vote is merely a popularity contest and the citizens' vote has no actual power to make a president.
