All the comments here are on her not being progressive enough, but the poll doesn't really indicate which direction voters want to go. It's just as possible they want her to be more conservative, especially since Trump tends to win polling on most issues, like immigration and the economy. 

Also, the fact voters in this poll say Trump has more detailed policies than Harris is a little tough to swallow. That's just flat out not true. Honestly I actually doubt most Americans have even looked into either of their policies in any real detail.
