“There is hard data that shows that a centrist Democrat would be a losing candidate:
Economist Thomas Piketty wrote a paper about this in 2018, though the Democrats paid no attention. The Republican Party has earned a reputation as the anti-science, anti-fact party — understandably, perhaps, given the GOP’s policy of ignoring the evidence for global climate change and insisting on the efficacy of supply-side economics, despite all the research to the contrary.
Yet ironically, it is now the Democratic Party that is wantonly ignoring mounds of social science data that suggests that promoting centrist candidates is a bad, losing strategy when it comes to winning elections. As the Democratic establishment and its pundit class starts to line up behind the centrist nominees for president — mainly, Joe Biden, Cory Booker and Kamala Harris — the party’s head-in-the-sand attitude is especially troubling. […] Piketty’s paper is an inconvenient truth for the Democratic Party. The party’s leaders see themselves as the left wing of capital — supporting social policies that liberal rich people can get behind, never daring to enact economic reforms that might step on rich donors’ toes. Hence, the establishment seems intent on anointing the centrist Democrats of capital, who push liberal social policies and neoliberal economic policies.“. – Via Salon
