She lost.

If you liked her, that is fine, sorry for your loss. But, I think this quote from you sounds delusional.

If you were arguing she and her party's policies and record were deeply unpopular, and could not be overcome by even a great campaign, I'd give you that. But, I don't think she had a good campaign.

She alienated vast swaths of voters.

She lost Michigan because of her policy of continuing to enable genocide of Palestinians by Israel and she, and her party, being actively hostile to any who speak out, even mildly, against it.

At a campaign stop, she responded to a woman who had told her she was recently made homeless because of medical bills, that if she were elected, she would would prevent medical debt from being reported on credit reports. This makes her sound almost as out of touch as Romney famously admitting, during his presidential run, that he'd never stepped foot into a grocery store; that was a duty for his servants.

In an interview, she said, she couldn't think of a single thing she would change from Biden's policies. Her lack of proposals to help the working class, and her promise to maintain the (painful) status quo, lost her the majority of working class families, throughout the country, to Trump-- The status quo is not good for the majority of Americans. Harris effectively told working class Americans, that they will continue to struggle and suffer if she is elected-- working class America took note, and the majority, all across the country, voted for Trump (he may be just as bad, or worse, but he didn't promise to keep things terrible; I believe he will be, at least, as bad, but he represents some small hope that things might get better, for a lot of Americans).
