The Democratic party refused to understand that courting the right doesn't work, and now it's cost them the election

Centrism can win in places that aren't America. Too many Republicans are being fed propaganda all day long by Fox "News"...an organization that has argued in court that no one should take them seriously. But that's where they get their news. They're also indoctrinated by their religious upbringing from Evangelicals. There is no such thing as a moderate Republican anymore. They have shown that they will vote every time for the Republican candidate regardless of how flawed they are. Trump is a convicted felon that tried to overthrow the government, has been found in a court to be a rapist, was best friends with Jeffrey Epstein, has had numerous failed businesses and bankruptcies, has denigrated our troops. NONE OF IT MATTERS. Stop trying to appeal to the right and actually get your voting base excited about the policies you want to push.

- There is no center in the US. If you're okay voting for Donald Trump, you are not in the center. That's entirely the point.

Keir won because the U, like the US, has First Pass The Post and the Even More Far Right Party - Reform - divided the votes on the Far Right hence the Tories came second in lots of electoral circles were they usually come first.

Also I've lived all over Europe including the UK and New Labour is plain Right, not Center-Right - they only seem center by comparison with the Tories who migrated to the Far-Right during the Leave Referendum and subsequent Johnson Government.

Similarly by comparison with most of Europe (not the UK) the US is a country with only a plain Right (maybe even hard) and a Far-Right.

Curiously, both New Labour and the Democrat Party support the ethno-Fascist regime in Israel, something which I feel neatly underlines my point as from what I see elsewhere in Europe (with the notable exception of Germany) no Leftwing party supports them.

- Labour are centre-left within the context of British politics
  Nothing left about them, Keith made pretty damn sure of it. The fact that you (and sadly many others) think they are though, is simply a demonstration of how the Overton gets shifted to the right by the establishment protecting its own interests, since they are who parliament actually serve.
  maybe this is the wrong community for me to say things like that.
  Pro tip: the community you post in doesn't change reality.
- Or maybe the words do have reasonably fixed global meaning and only British Exceptionalism and their very propaganda-heavy environment makes Britons think their political landscape redefines those words.
  Besides, even in Britain you might want to consider the existence of the Corbyn phenomenon (who, if I remember it correctly, got more votes than Starmer did) as well as the Greenparty (whose 1 million vote count went up to 1.4 million in the latest electing) as proof that there is in fact a Left even in England which is not just "What's in it for me?!" Neoliberals cosplaying as "lefties" by throwing some identity politics slogans and below inflation minimum wage raises once in a while, whilst de facto supporting an ethno-Fascist regime half way around the globe currently working on Holocaust v2.
  I would say their support for the Neue Nazis and their pro-Finance politics (which I saw up close and personal having worked in that Industry before, during and after the 2008 Crash) by themselves are more than enough to place them firmly in the full-on Right field, possibly even Hard Right.
  People whose guiding principle is "The greatest good for the greatest number" don't do what the New Labour types have done and continue to do, even the "pragmatic"/"moderate"/"center" ones.
  
  What would I know, my references are only politics in 4 different countries including being a political party member in two of them, one of which was the UK ...
  
  For avoidance of confusion, I'm talking about New Labour, not traditional Labour.
