In the wake of November's midterms, members of the Democratic Socialists of America – a leftist organisation that's made inroads within the Democratic Party – now lead cities across the country, including its two largest, New York and Los Angeles.

DSA-endorsed politicians boosted their congressional seats from two to eight and won dozens of local elections, victories partly due to the Democrats' wider battering of President Donald Trump's Republicans.
