More Clinton supporters voted for McCain than Bernie supporters voted for Trump

[Gracile]

Reposting from another thread:

As much as people like to talk about the stereotypical Sanders-Trump voter as being fervently anti-Clinton leftists, a good chunk of those voters were people who have effectively been Republicans for several elections (at least on the presidential level) but voted in the Democratic primary as it was their registered party in a closed primary state. Their vote for Sanders was largely just a protest vote against Clinton.
