A bigger difference is that Hillary was married to Bill Clinton. No matter what we think of him, Bill was / is popular with democrats (especially before Obama tore America apart along racial lines and now some lefties consider him racist). The ONLY reason Hillary Clinton is anybody is because she married Bill Clinton. Period. But that was enough to almost make her President.
Harris keeps her husband hidden behind a curtain because ... white. Not an asset at all politically. She was picked for the job she has, she didn't earn a single vote, not in primaries or in the general election.
And yet she'll end up President most likely even though nobody likes her or voted for her.
There is only one way that happens. Well, maybe two.
