from my point of view, she made a few mistakes: 1. She never differentiated herself from Bernie - this was critical to her success. She should have positioned herself as the candidate that bridged the gap between the moderates and the progressive. Progressive Social Policies married to Capitalism. But instead she went with "I'm with Bernie" 2. Well that worked until she freaked everyone out with her M4A plan. People do not pick candidates based on their policies. The more specific you get, the more ammo you are giving to your rivals. Just pick good, general plans that are kind of vague and non-specific. People pick their candidates based on their person, ethics, morals, personality, effectiveness, and whether they believe in them.; 3. And then when it was time to start pointing out the differences between her and the Bern, she chose to attack Bloomberg over and over and over again until it started feeling way too personal. She didnt realize that she was helping Biden and hurting herself. She should have been balancing her criticisms of Bloomberg with showing how she is different that Bernie and Biden. I love her and thought she would make a great president but she made lot of tactical mistakes along the way.
