She lost for one simple reason: Middle class and working class Americans knew that the country is broken and that The Big Guy and Kommie were the ones who broke it. They knew that Kommie helped break it when she acknowledged in an interview that she wouldn't have done anything differently than The Big Guy and they knew it when The Big Guy acknowledged in an interview that Kommie was a vital part of every decision he made.
IOW...the middle class and working class didn't want four more years of Biden's puppet masters.
