The two party system isn’t the only problem though, there’s also:

• Money being a form of speech – EU MEPs aren’t soliciting billionaires for money to spend on TV ads
• The 10th amendment – prevents any national effort where the federal govt uses a power not explicitly granted to it in the constitution. Obamacare tripped up here for instance, and Obamacare is far from national socialized healthcare. It was a feature when people identified more with their local culture, but in an era when every American identifies as American-first, and engages the political system accordingly by only knowing or caring about national candidates and parties, it becomes a bug.
• States that should have never been states – the US Senate took a heavy rural turn in the 19th century as vast, sparsely populated territories were given statehood. Nowadays this means to buy two US Senators you only need to gaslight ~600k people with advertising (the population of Wyoming). The founding fathers never really developed a solid plan for how the west would be settled, and it shows.
• Powerful and unaccountable Court – the Supreme Court is given authority over both other branches, serving life terms, with few guidelines or restrictions. A party with the Presidency and Senate at the right time can gain a majority of the court and undo (or manufacture) precedent at the snap of a finger. The resulting system makes it far easier to capture the court than to pass a constitutional amendment. Think abortion should be legal? Here’s a roundabout legal justification for that. Oh the new majority thinks it shouldn’t be? Okay now it’s gone. It’s a chaotic way to handle bedrock rights like access to healthcare and privacy (neither of which are mentioned anywhere in the US constitution). The constitution should be malleable enough that the court is strictly tasked with interpreting the letter of the law. The US shouldn’t be relying on legal gymnastics to legalize abortion and gay marriage. It’s unstable and undemocratic.
• Electoral College – the leader of the country, not just the Executive but the Head of State, is elected in a way that respects statehood more than personhood. It is more concerned with making sure Wyoming gets a fair vote than making sure John Doe in Queens does.
• First past the post voting – this is another oversight by the founding fathers that many European republics were able to avoid, and it’s the root cause of the two party system. But it also makes gerrymandering possible, which completely breaks both state-level politics and the US House. It makes so many seats into “safe seats” that the “money is speech” briberies become much easier to allocate.
• Racism – almost every dumb thing about American politics can be traced back in some form to slavery, segregation, or racism. Why is every state given 2 senators? Slavery. Why were some of those rural states admitted? Also slavery. Why did White Americans support progressive policies in the 30s, 40s, and 50s? Segregation. Why did the entire Deep South flip from Democrat to Republican in the late 60s? Also segregation. It’s America’s original sin and it’s still playing a role.

Every one of those things plays a role in the US not adopting stricter privacy standards, or leading the way in anything except military might. It’s why American politics is so broken that even a majority of voters wanting to fix it isn’t enough.

The European Left needs strong support.

Well yeah, no one has ever used the term “only hope” optimistically lol
