the Democrats are a primary party in a military cult empire that indoctrinates children with flag rites and coups every government that dares to call itself socialist. I'm guessing you're part of that military cult and thus don't understand how insane it seems from the outside.

There are left elements, that sandy man seems to flirt with Democratic socialism, although not very strongly. It doesn't seem like he has much power though.

Labor in the UK has thoroughly remade itself after Thatcher with the new labour movement which distanced themselves from their unionist and socialist roots. They now don't have any particularly leftist policies, although they are less right than the Tories obviously.

In Australia labor did a similar thing after the USA couped our only elected socialist government and replaced the labour leader with a CIA groomed dude.

The right is utterly ascendant in global politics and has been since the rise of neoliberal economics under Reagan and Thatcher. That power is beginning to wane, but don't confuse being left of "we should hunt the homeless for sport" with being a leftist government. Leftism isn't when shouting slurs gets you tutted at, it's Democratic businesses and worker owned collectives, nationalised infrastructure, anti imperialism, open boarders, welfare above the poverty line, universal recognition of human dignity etc.

In Australia the most mainstream leftist party would be the greens who hold at most 1 to 3 seats out of 150 regularly. Similarly in the UK I am given to understand. There are more radical parties but they're even more marginalised.
