That’s the problem. She has failed just about every task iirc and worse, bitterly and loudly and PUBLICLY complaining that it was even assigned to her in the first place. She did remain in DC to be a tie-breaker but that’s a bare minimum. She’s not nothing but those aren’t typical qualifications for someone running to be the leader of one of the most powerful nations in the world… i.e. she wanted to stand up and be counted but she seems to enjoy being asleep on the job.
She’s not Trump, and she’s not as old as Biden. And people in the center who might have voted either way are going to be asking themselves what she brings to the table, over Trump who is also very old and will also have his own VP. I’m not the best at understanding that mindset - I think it goes something vaguely like “ignoring everyone else bc they don’t matter at all, and also ignoring the future, and also ignoring most facts, what do I think will work out best, in the short-term, for ME?” And unfortunately a Biden+Harris minus Biden holds little appeal.
Meaning that some of those will vote Trump. Sorry, I’ve lost most of my own hope. But we’ll see what happens - there’s lots of time yet.
