The main problems contributing to her loss were: - Russian interference - Huma Abedin - Fake News - James Comey All of those factors can basically be eliminated before she starts another campaign. Russia: We have to improve our defense against cyber warfare. Not handing out your password to phishing sites/emails would be a great start for example. Huma: Just fire her. Fake News: They're already solving this issue with the help of Facebook, Soros, politifact etc. Comey: Don't set up your own e-mail server. A mistake she won't do a second time. Also, Trump might fire Comey anyways. One way or the other she won't be under FBI investigation for her emails in 4 years, that's for sure. With those four main reasons for her loss out of the way, she should have a great to chance to become the first female president of the United States.
