@coldjoint,
I think 4 years past the email scandal, coupled with Trumps dumpster fire presidency and embarrassment across the country and globe, and renewed fervor and lack of complacency on behalf of left-leaning folks...would lead Clinton to a victory.
She was only 50,000 votes away from winning last time, and Trumps only gotten worse, while Clinton's approval has gotten better (and will continue to get better as she holds no political office and won't have the baggage with what that entails).
She won't be the nominee though. If she runs, she'll lose the primary.
