That's cute, you're actually taking those polls at face value. If you honestly believe support wouldn't drop dramatically when people find out that many of those policies require higher taxation (especially among white people after they realize that those policies benefit minorities), you don't know what you're talking about.
Just because your incompetent media spread irrational fear about taxes for decades, just because they acted fo decades like Republicans were fiscally conservative, even though its always been the democrats who brought down the deficit while it was Republicans who drove it up, doesn't mean that people wouldn't quickly change their minds about social systems once they see them working.
It's all about optics and framing. Americans do no hold any rational convictions here that would prevent a welfare state of European proportions.
Decades of propaganda that was forced down American throats will be undone in no time once people realize that this is good for them and everyone around them.
And don't believe for a second that corporations would leave the country if you increase their taxes.
Besides that, Europe and many other players would be up for strict international tax codes and laws and mechanism preventing tax evasion.
Corporation know that, which is why the spend billions upon billions bribing politicians and spreading propaganda through the media in order to prevent sensible legislation and international corporation.
This shit has nothing to do with voters.
I don't disagree, but none of your points change the fact that
far more Americans identify as conservative. A multiparty system wouldn't change that, nor would it magically solve the partisan divide that doesn't interest you.
A multiparty system would change that in no time because it would immediately change the kind of political discourse you have.
Multiparty systems require parties to find common ground and compromise, while two party systems incentivize divisiveness.
It would complete change the framing of all the issues the US debates and if money has been removed from politics as well this would take away the strong power of business interests which are currently dominating.
As to point #4, if leftists aren't represented in this country, it's because the politicians are too conservative (something you'd expect from a conservative country) or because there aren't enough leftists running for office and not enough leftist voters to get them in (again, because this country leans conservative).
The country isn't conservative. The country simply has a system that grotesquely over-represents conservatives.
With Bernie Sanders you can see how even the supposedly "left wing" media is attacking moderately left ideas.
How even the Democratic party is gatekeeping in order to prevent moderately left ideas form entering the sphere of debate.
And your elected officials and media are so bought by big business that they vote down anything thats not in the immediate interest of businesses and make it seem like it is extremely unpopular, even though its only unpopular among the donor class, but they have all the power.
If you really want to change anything for the better in the US, you need to chance the system, otherwise you are fighting an uphill battle you can never win, because the system is rigged - plain and simple.
Do you know why? This is not a "Leftist" (I prefer Progressive) Country
Why wouldn't it be?
If it wasn't progressive, why would you need to rig the system to over represent conservatives?
Why would corporations need to spend billions on bribing politicians?
Why would media outlets work tirelessly to frame every issue in a certain way to people adopt a certain kind of viewpoint thats in line with corporate interests?
If the people already inherently held these views, none of this would be necessary.
