I talked with her class president in High school and although he never used the term Hubris, I believe everything he said about young Hillary fits the definition. This is her weakness. She is literally brilliant. Much of her problems arise from underestimating her opponents. She did this with President Obama in 2008, and she is doing the same thing with Donald Trump. I think she could kick asz if she displayed humility to the American public, but for a women to break the glass ceiling there is NO room for self doubt and her Hubris is entirely understandable, but she needs to recognize that good people......not just crazies pick up this attitude. I am not asking her to pretend to be humble, but she needs to quit being that young girl who is the smartest in class continually raising her hand to brown nose the American public......I want to see naughty Hillary.....vulnerable Hillary.....funny Hillary.....I want her to relax and just quit fighting that battle......all her closet friends say she really can be charming.....just get real and America can fall in love with her.
