Your delusional if you think there wasn't any fraud done. And doesn't matter the margin. Fraud should upset any proud American. I got two ballots. One in NY and one in NJ. I did not use both because I'm a law abiding citizen. I'm 100% sure people with more animosity towards a specific candidate didn't hesitate to submit both.
So yes. Even if the margin is not enough to win. It is ok with being angry at the system. Not to burn down the whole country, or kill cops, or loot stores, but enough to protest
+1.
I know many people who got mail ballots for deceased people (one deceased for decades) or members of household no longer living there. Even if not, and all the ballots sent were for actual people that lived there, all it takes is one member of the household to fill them out for everyone, even though most of the household members wouldn't have bothered voting. It stands to reason that there was a nice amount of invalid ballots submitted. Even if these people usually wouldn't go out of their way to commit fraud, over here it was handed to them on a silver platter, and would take a good deal of self control to abstain.
Note: I'm generally not a conspiracy theorist, and I don't know if these tilted balance in election or if any one party had a higher incidence of fraud, but I think it would be gullible to assume it's one in a million.
