And Trump was??
By what yard stick is Harris unelectable but Trump is electable. Trump is a felon and possible pedophile who is known to have partied with Putin, and who is known to put himself ahead of everyone else. He has no experience with international diplomacy. In fact he understands nothing about people and culture and has demonstrated that many times, and has shown every sign that he in fact hates everyone except for him.
I'm on pins and needles to know what was so bad about Kamala Harris that she was even worse than that. I'm speculating that you actually have no idea what is required to work with other countries at a national leader level as that is the only thing that can possibly lead to your conclusion that Kamala Harris was less electable than Donald Trump.
