What about Joe Biden made him sufficiently left while Kamala Harris wasn't?

-Joe Biden wasn't campaigning to finish building Trump's wall. Or saying that actually it was a good idea to build the wall and the only problems were just that Trump said Mexico was going to pay for it and that he didn't finish the job.

-Joe Biden wasn't campaigning on being pro-fracking. And bragging about how he was the tie breaking vote for the IRA, which leased new land for fracking. (I understand there was more to this act, but Harris points to it as a way to show she supports fracking)

-At the time the genocide in Gaza hadn't ramped up and gotten as much publicity as has now, so we didn't get to hear Joe Biden's stance on it.

-Joe Biden wasn't calling to ensure America has the "strongest most lethal fighting force in the world".

-Joe Biden didn't align himself with the Cheneys.

You see that 10 million more Democrats voted for Biden, but stayed home for Harris and you believe the problem is with the people and not the candidate? Now granted, racism and sexism played a role in this for sure. But to attribute that much of a difference just to that? Most of the people that are deeply racist and sexist are already voting for Trump because he supports those ideas. And from what I've seen, the Republican voters stayed pretty consistent from last election. It was mainly a dip in Democratic voters. If the problem is with the voters and not just that Harris was an incredibly weak candidate, then why do you believe that many more people voted last election?
