Seeing poll watchers thrown out, and the number of statistical anomalies seemed fishy to me. Signatures were not checked. The results took days to settle. Why? - but what do I know? I'm just a Brit.
Once the election was over everyone was very hasty about declaring it for Biden, without addressing any of the concerns.
The whole point of an election is about trust and transparency to prevent chaos.
People should be allowed to question things without being demonized.
