Hillary Clinton lost because of her emails. Not the leaked Podesta emails. Not her personal emails. Not because of bleaching or a secret server. She lost because of HER FUNDRAISING EMAILS.
Her email marketing strategy was simple: email constantly asking for money, lie in the emails, and don't really ask for any other support.
I donated $1000 -- and received an average of 4 fundraising emails per day in the week before the election. Four Per Day. No wonder everyone tuned her out.
And they were bad fundraising pitches; I expect that some of them were, as a matter of law, MAIL FRAUD. "I’m personally asking you" - no you weren't. "We need 7 more people from San Francisco" - you aren't counting. "this is me, personally asking you" - another lie.
You may ask "why didn't you just unsubscribe". THAT IS THE PROBLEM. If Hillary Clinton ran her marketing campaign expecting everyone to unsubscribe, she was unable to communicate with her supporters.
Any candidate who does this in the 2020 cycle will not have my support. For more thoughts about 2020, please check my blog at pow3.com
