Hillary could be Gerald Ford and Bernie Sanders could be Ronald Reagan. Hillary narrowly wins the primaries against Bernie in 1976 and loses to the GOP candidate, and Bernie wins in 2020 and ushers a liberal era. Just like how Ford narrowly defeated Reagan in the 1976 election and lost to the Dem candidate, and Ronald won in 1980 and ushered an era of conservative dominance.
That's interesting, I just had a similar thought today. Both the Democrats of 76 and the Republicans of 2016 had a larger then usual field. While he doesn't have the similar outsider label I wonder if Jeb Bush would be a good analogy for Jimmy Carter in that both tended to be distrusted by their parties base.
