The "stolen election" thing is just sooooo stupid. Lets just say it is.
It's a childish, made-up event to pander to grown men and women that are so used to being politically pampered that glaring truths hurt them.
Trump was, is and will never be a popular President amongst most Americans. He never came close to winning the popular votes in any of the general elections.
This stuff is very easy to understand and doesn't really require any more analysis.
