I'm not asking for a perfect candidate, not sure where you got that from.
My whole point is that Harris' positions got her some number of voters. We now know that this number was too small, and we also now know that they knew this fact.
Harris could have changed her positions to get more voters, but she didn't. How is this not completely her fault?
Again, I'm not asking her to be some perfect politician. I'm asking her to look at the polling results (which we know she had) and to adapt her campaign based on those, which she didn't do.
