There are three things that could derail Trump in 2020 and they are in order of magnitude:
1. Voter fraud
2. Voter fraud
3. Voter fraud
The time is NOW to head this off in every single State. Now you know why Soros spent so much money on getting secretary of state positions in the hands of the dems.
I have also read (some place) where he has large stock holdings in voting machine companies.
Maybe a firmware update just before the election to re-arrange the votes.
Then a firmware update to put back the original system.
Would not surprise me at all.
