The Democratic Party of the US is NOT "left wing".

It's to the left of the Republican Party, but that doesn't make it "left wing".

If you judge the Democratic Party by its policies, its closeness to big money, and their hawkishness, the Democrats are center right at best.

The "Overton Window" in the USA is heavily titled to the right, which should come as no surprise considering the USA was created by slavery, genocide and land theft.
