Whilst the left has certainly moved, it is also the case that the right has moved a lot, too. Politicians like Trump, Farage and Le Pen are mainstream and are far more right wing than their predecessors who called themselves conservative.
Not really. They're all either comparable, or even to the left on many social issues than many left-wing parties were 10 to 20 years ago. Trump supported same sex marriage before Obama did and none of the above want to undo it. They also have pretty similar ideas when it comes to immigration, compared to past left-wing governments, when mass-migration from low wage economies was seen as something which benefits big business, at the expense of the working class.
Agreed.
Trump's Democrat supported activities and stances:
Trade Protectionism (canada paid 70milion to run an ad on US TV (who watches that) having Ronald Reagan call out Trump on Tariffs)
Spending
Tax Exemptions for Workers (Tips and overtime)
Drug Pricing Controls
Full support for Social Security and Medicare; he hasn't supported privatization or cuts.
Infrastructure spending
Criminal Justice Reform (The First Step Act)
His written (Book) views are "pro-choice"
Also, his writing supports universal healthcare. (Though he wants to reform and build on what's been attempted in the US)
The most "right-wing" thing he's done is "America First/Popularism"
And, I'm not sure this should be "right wing," but he's been a strong supporter of enforcement of the law.
Today, most folks who study these things don't place Trump on the scale most people use as a lens.
He and his movement are considered "Populist Disrupter." Many would place Trump closer to the center than Obama, but again, the whole left/right scale has shifted far left and spread the left very widely from the center. The scale shouldn't be viewed as 50|50 in ideological distribution. This goes to the image I posted earlier that, I believe, and that the research supports, shows the "left" has raced away from the center.
Again, the ideology is why we have this topic going on an EE Forum. Who would have thought that a few years ago?
