Yes, misinformation and misunderstanding was a problem. But would misinformation have won the day, if we actually had a more democratic system in the first place?
To wit:
* Electoral college
* Plurality winner system (vs. a run-off system where the winner would have majority preference, which now could be done by RCV or similar)
* gerrymandering, which is getting much worse with the death of the Voting Rights Act. This enables the Republican-majority states to overweight their U.S. congressional delegations.
* U.S. Senate allocation equal to all states regardless of size. Meaning small states get an outsize advantage in crucial government decisions.
* Voter suppression tactics tilting the demographics of who votes, and whose vote is actually counted.
* Who counts the votes, and when. (see the Great Mail-In Voting Debate: forcing states to start counting mail in ballots late, creates a false perception of unfairness in the minds of voters, when beginning the count earlier would remove the late "shift" affect).
