The point is that most European countries have a left-wing. The US does not. The Dems are center-right… center at best. The DNC has put a strong effort into shutting out the more progressive members of their party in the interest of the status quo.

In recent decades, the closest thing we’ve had to genuine left-wing American politicians at the federal level is Bernie Sanders and Tulsi Gabbard, and they’re not even that far left. Both are registered independent, not Democrat.
