Looking at the Democratic primary as a movie, a film critic might say that Sen. Bernie Sanders is a little “on-the-nose” as an antagonist to Hillary Clinton. He is her reverse. Where Hillary is well-known (and to many women, an icon), he is obscure. Where she embodies the establishment, he is on its outskirts, a self-identified “socialist” from the liberal enclave of Burlington, Vermont. Where she gives six-figure speeches, he is among the “poorest” members of the Senate with a net worth of roughly $460,000. She plans to run a $2 billion campaign; he hopes to raise $50 million.
