You notice, Kamala never said what she would do for the country except in the broadest sense. What little there was of her campaign was about Trump.
Therefore, we can only assume, the votes she did get, weren’t for her, but against Trump. That means most any democrat could have done as well or better. My guess is, much better.
It’s kind of what happens when you have nothing to offer the voters other than, “I’m not him.”
