Mail-in or drop-box voter fraud is exceedingly rare because of system checks and balances, according to the Brennan Center for Justice. However, there’s a big partisan gap in such voting, as 48 percent of Democrats compared to 27 percent of Republicans said they intend to vote that way (Trump himself voted by mail in the Republican primary elections).

While fraud might be rare, mail-in ballot delays could be a huge problem. During the Republican and Democrat primaries, over 550,000 mail-in ballots were rejected, compared to 319,000 during the entire 2016 general election. Many of those ballots were refused because they were late.

Since then, the USPS has cut back even further on services and taken hundreds of voting machines out of commission. Voters in Michigan and elsewhere cited those as a reason for voting by drop-box instead, according to NPR. Drop-box ballots are collected directly by election officials and thus can’t be delayed. (Also, COVID-19 is much less likely to be spread by a touching a virus-infected surface than by other means, according to the CDC.)

Twitter has placed warnings on Trump’s tweets about voting before, but hiding one is a more noticeable action that’s bound to draw the President’s attention. After he was fact-checked for a false tweet and “manipulated media” earlier this year, the President signed an executive order designed to limit protections for social media companies. Facebook, meanwhile, has left Trump’s Sunday “voter security disaster” post intact, with merely a label about voting information that it puts on all its election posts.
