Bernie Sanders lost the fight in 2016. A decade later, he won the war.

What happened: Bernie Sanders said the economic populism he ran on in 2016 proved a winning formula in the midterms, with candidates echoing his message winning in states such as Texas, Ohio, Montana and Florida. Why it matters: Sanders and strategist Morris Katz said Democrats should keep an affirmative economic message, arguing that attacks on cultural issues failed where candidates defined themselves on economics. Key numbers: Sanders held over 20 rallies in October alone and is 85.
