“During this period, there were 109 different Democrats who served in the Senate and cast a sufficient number of roll call votes for a reliable analysis of their ideological position. Of these 109 Democrats, Harris has the second-most liberal voting record. This makes her slightly less liberal than Warren, but more liberal than all of the remaining 107 Democrats, and significantly more liberal than all but a handful.”

Harris is a party-line voter (pretty obviously, as an insider she's defining the party line in the first place). The Democratic Party isn't leftist and nor is Harris. It's routine in most democracies for elected representatives to be party-line voters.
The DNC's bread and butter are Liberals. Not Socialists. Not anyone even approaching Socialist. Bernie, AOC, etc are SocDems at best. There are no Socialists in office in the United States.
Americans don't want to pay European style taxes even for European services. And our public sector is far less efficient than Europe's so we wouldn't even get European level of services for that taxation rate.
"The DNC's #1 goal is to stop democracy in the primaries."
FTFY.
