OP asked me to name "the Democrats trying to replace capitalism." I think it's fair to say that Sanders and Ocasio-Cortez and other DSA-affiliated Democrats are trying to do that. That is not an assertion that Democrats as a whole want to do that.

Only 47% of Democrats have a positive view of capitalism, versus 57% having a positive view of socialism. That's shocking for the party of Bill Clinton and Barak Obama. There was a time when socialism was a dirty word in America, and it was for a good reason. When my dad was born in what was then Pakistan, India had similar per-capita GDP to South Korea. Today, thanks to flirtations with socialism, India is still quite poor, while South Korea is as rich as France: https://reason.com/2006/06/06/the-rise-and-fall-of-indian-so....

This is the 1996 Democratic Party platform: https://www.presidency.ucsb.edu/documents/1996-democratic-pa....

> We need a smaller, more effective, more efficient, less bureaucratic government that reflects our time-honored values.

> We support government policies that encourage private sector investment and innovation to create a pro-growth economic climate, like a permanent research and development tax credit.

> Today's Democratic Party knows that the era of big government is over. Big bureaucracies and Washington solutions are not the real answers to today's challenges. We need a smaller government . . . and we must have a larger national spirit. Government's job should be to give people the tools they need to make the most of their own lives. Americans must take the responsibility to use them, to build good lives for themselves and their families. Personal responsibility is the most powerful force we have to meet our challenges and shape the future we want for ourselves, for our children, and for America.

> Welfare reform. Today's Democratic Party knows there is no greater gap between mainstream American values and modern American government than our failed welfare system. When Bill Clinton became President, the welfare system undermined the very values -- work, family, and personal responsibility -- that it should promote. The welfare system should reflect those values: we want to help people who want to help themselves and their children.

> We have worked hard over the last four years to rein in big government, slash burdensome regulations, eliminate wasteful programs, and shift problem-solving out of Washington and back to people and communities who understand their situations best.

> In the last four years, President Clinton, working with the National Performance Review chaired by Vice President Gore, has cut the federal government by almost 240,000 positions, making the smallest federal government in 30 years. We did it the right way, treating workers with respect. The federal government is eliminating 16,000 pages of outdated and unnecessary regulations, has abolished 179 programs and projects, and saved taxpayers billions of dollars.

Watching the debates it's impossible to see any hint of that party.

> The two Democratic front-runners are Biden, who represents a continuation of Obama's moderate economic policies, and Warren, who famously said she's a "capitalist to her bones".

Given how quickly the party has distanced itself from Obama's moderate-conservative economic policies, I'm not sure how great I feel about 76-year-old Joe Biden was the firewall between me and 1960s-style European socialism.
