I'm personally of the opinions that elections are not stolen but I do think any candidate has the right to challenge the results. Hillary whined and wrote a book. Trump staged a protest that turned into a riot.
As for Biden, if I was him, I would have one of my secret service agents stand behind me every time Kamala is in the same room. I'll always believe that the JFK assassination as well as that of his brother were democratic operatives working with the mafia to remove these two from power positions. I've read no fewer than a dozen books from various perspectives as well as watched hours of video and this was no lone nutjob in a book warehouse or some loon from the middle east. Both of these murders were planned and meticulous hits.
