The Fascist GOP have been whittling away at rigging the electoral system for decades and the Dems have been ignoring it.
All of this did not just happen since Trump:
E-Voting machines (and optical scanners) with proprietary software
polling place reductions
Drop Box reductions
Early vote reductions
Media Blackouts
Complicit Media
Canceling vote by mail
Torturing people waiting to vote (denying food or water)
Citizens United
Judges rated “Not Qualified”
cheating,
hacking,
gerrymandering,
Interstate crosscheck*
Emerdata Limited (formerly Cambridge Analytica)
Voter Purges
Electoral College
hamstringing the USPS
And MOST of that is still in place and operational.
