Sen. Chris Murphy said Sunday that Democrats should welcome democratic socialists into the party and argued that the current form of capitalism cannot be sustained, calling for the party to be a 'big tent' that includes candidates from the socialist wing. The comments reflect growing intraparty tensions between moderates (like Pennsylvania Gov. Josh Shapiro, who explicitly distanced himself from democratic socialist candidates) and progressive-left figures embracing socialism as a policy framework. Murphy's framing of capitalism as unsustainable represents a notable shift in mainstream Democratic rhetoric, though he stopped short of endorsing socialism itself as party policy.
