I mean what has she done other than cast tie-breaking votes in the Senate?
What are VPs supposed to do?
Well Biden himself is a great example, he connected with the public in a way that he would've never been able to win the nomination four years after leaving office if he didn't and sort of served as the unofficial spokesman for the Obama Admin.
But as for Harris...well get this she's actually visiting Minnesota this week. But it's in St. Cloud, not even the Twin Cities, and isn't getting much attention outside of the St. Cloud media. And remember St. Cloud isn't that far, Twin Citians could easily commute, but there really just doesn't seem to be much interest at all. She probably will pull a smaller crowd than Keith Ellison could pull.
