Bad word choice. There is corruption on both parties, but saying it's rampant is just objectively not true. When the numbers are so different between the two, statements like yours are just both sidesing the issue and effectively softens the criticism towards Republicans.
Name and shame the individuals rather than 80% of the party that didn't vote for this.
Or maybe citizens can take steps like going in person or dropping their mail in ballots off directly instead of conceding. There's no doubt Republicans will try to steal the election, but that doesn't mean that their efforts will be successful. It won't be convenient for many, and may be difficult for others, but being proactive is far better than being reactive when it will be far more difficult to get change.
