This really is ridiculous on multiple levels. Even if it was proven the election was stolen from Trump, he doesn't magically return to the White House. Biden would have to be impeached, and then Kamala Harris would become POTUS. Ex presidents aren't in the line of succession, no matter how many in line are impeached.

They know this can never happen. It's a ploy to get stupid people to part with their money.
