As somebody not from the US, the mainstream "left" seems very right wing. When compared to the rest of the world, there is no left wing political party in the United States.
Well, this is an international forum, so I think it's a good idea to remember that many people reading are not from the same country and may have different interpretations of some terms. Also, maybe looking outside and gathering new data once in a while may put the problems you percieve your country to have in broader context, and help you find new solutions that actually work.
I take it you haven't read the Party Platform, have you?
Not sure that it really matters. As the #1 and #2 priorities of the Democratic Party right are allowing for the unrestricted killing of the unborn and supporting the alphabet-soup of sexual/gender spectrum.
But your #1 and #2 don't appear in most countries non-extremist left parties. Sure many other western democracies allow abortion in some form, but never unrestricted. E.g. in Germany you can abort in the first three month of the pregnancy if you have been to counseling. That makes it impossible to make a decision in a moment that you would regret later. Later abortions are legal only in life threatening situations.
And the support of logically inconsistent and outright vile policies to favor the later letters of the alphabet soup are an American export.
