The Democratic Socialists of America released a new party platform this week that would fundamentally remake the U.S. constitutional system, calling for the abolition of the Senate and the replacement of the presidency and Supreme Court with bodies subordinate to Congress.

The manifesto comes after a series of primary victories by DSA and progressive candidates, reflecting the organization’s renewed energy and long-term plan to replace what it argues are undemocratic institutions with a government more directly accountable to voters. Central to that vision is eliminating the Senate, which the group argues gives disproportionate political power to less populous states because each state receives two senators regardless of its population.
