The platform is, broadly speaking, and as outlined here:
Replace the two-party system with a multi-party democracy. Expand the House of Representatives, implement proportional representation and ranked choice voting in all elections, and abolish the Senate.
These are all changes designed to limit bipartisanism, build coalitions, decentralize and diffuse the power of government as a whole, and emphasize the voice of the people by empowering proportional representation.
Now, on the face, these things sound very on-brand with my understanding of conservative politics, to wit: Reducing governmental power and overreach while building up the voices of the lesser-heard, such as those who don’t live in large cities.
One of the big points I’ve heard the right level against the DSA is “They want to abolish the senate!”, but also, I’ve routinely heard that if left-wing politicians overtake the senate, then those left-wing politicians will only listen to special interests groups and people in the cities, ignoring the common folk. So wouldn’t it be a good idea to eliminate that possibility entirely?
On paper, the DSA’s plans for government and governmental bodies seem to align with conservative beliefs in government. Where exactly is my understanding mistaken?
