Did the Russians hack the DNC email server?
Did the Russians hack election systems in a number of states?
Did someone spend a lot of money trying to "convince" voters the election was hacked?
It was hacked. Did they change any votes? Unknown. Did Trump encourage the Russians, even with a vague statement about their finding emails from Hillary?
Remember that it was pretty obvious that DNC emails were being released by Wiki in an attempt to help Trump.
Is it outrageous that many voters would question the outcome in 2020? What is outrageous is that Trump did. He started claiming fraud was going to happen in the summer of 2020. The lack of evidence that there was substantial fraud was ignored by Trump and his mob. Hillary Clinton conceded the 2016 election the next morning. Trump still has not done so.
You believe it was hacked, and therefore, suspect, no?
And if it was okay for you to question the outcome of that election, why is it not okay for others to question the outcome of the following election?
