What would change in the politics? How would the foreign policy be different? How about domestic policies?
Scotland is like Vermont politically, whereas the greater UK is perhaps Washington, Minnesota, California, New York or something. UK is generally liberal - even the Conservative party is more or less in line with US Democrats while the Scots politically feel much more Scandinavian than British. 
It makes me feel so uneasy the amount of things wrong with this statement.
If you think Cameron and the generic Republican have anything in common, then please arrest me.
I'm not even sure if Cameron is generally to the left or right of the generic Democrat, though he's probably slightly to the right. (Though Fredrik Reinfelt of Sweden is almost certainly to the left.
)
In Norway, every single major party supports the US Democrats, except for the very ultra hyper previously super racist far right party now in government - Progress Party, where it's about 50-50. Though Progress Party might be more like 60-40 due to its heavy focus not only on hating immigrants, but also hating taxes and regulations in general.
