"the Democrats have moved a bit left in the last decade"
You're rather understating things. Modern Democrats are a hair to the left of Tommy Robinson, and wouldn't even be welcome in the ERG. They have moved ever so slightly left, but they're still a party of protectionism, isolationism, and closed borders, as well as being (by UK standards) nutbar libertarian extremists on law and order.
It is staggering how large a difference there is in the fundamentals of politics between Europe and the US. Rees-Moggy would be somewhat to the left of Bernie Sanders and considered a dangerous communist.
