Incumbent Donald Trump is very concerned about possible fraud associated with mail-in ballots, but why? Although found to be negligible in the past, why would any fraud count against him? Why would any fraudulent attempt be made to favor the Democratic challenger, instead of the Republican incumbent? After all, Trump himself has made himself a role model for lying and cheating, from cheating on his golf score to having someone take the SAT for him. His faithful followers must like that, since they keep supporting him, no matter how much he lies, no matter what he cheats on, giving the impression that it is OK to cheat and lie if there is something you want.
Finally, it is the Republican controlled states that practice voter suppression by making it exceedingly hard for many to exercise their constitutional rights to vote. — not the more Democratic states. The truth is, that if everybody eligible were able to vote, Trump and many of his Republican enablers, would lose in a landslide. No wonder Trump is nervous. Although the vast majority voted for Biden, one has to wonder why so many still voted for Trump, after his dismal performance in every possible respect. That's how low they value the U.S. presidency?
