It's like the old Ginger Rodger's, Fred Astaire quote. Ginger did everything Astaire did. She did it backward and on heels.
Harris did pivot somewhat to the middle from 4 years ago in the primaries. Most candidates do. I would imagine 4 years in the administration also gives one a much different perspective than someone from the outside looking in.
She's running as a continuation of Biden's first term, much better than the chaos of 2017-2021
