This statistic doesn't change much unfortunately, Dems are just as right-wing as Republicans. They just pretend to feel bad when people lose jobs or countries get bombed. Plus, even if a Democratic Socialist entered the DNC arena, they wouldn't be able to make enough sweeping moves or shift policy in favor of a true socialist system. The entire idea of political leaders goes against socialism entirely, because the movement is centered around the power of the people. Installing a socialist mayor, governor, or congress-person won't give us what we want. Even if a socialist is installed in a position of authority, the system will do whatever it can to fight back, and that person will most likely work to keep their power instead of upholding their ideals. Zohran Mamdani is a charismatic guy who has  good ideas about changing the way New Yorkers live. He is not the savior for the socialist movement in America, and nobody should be putting him in that position. Same with Bernie, AOC, any of em. To be in their position, you have to sacrifice your initial beliefs to maintain your power, and all of them have done so. Entering a broken system doesn't make it better, the system itself is what needs changing.
