I think most conservatives have a strong idea in their mind of who their idealogical opponents are: ivory-tower academics, liberal business people and politicians, and all the plebs who side with them to push ideologies and social policies they don't want (policies like people born as men competing with women in sports).

Harris did nothing to distance herself from being strongly associated with that liberal cohort. Regarding social policy and ideology, she came off as being far-left to the average conservative.
