If I were to hear an American use a phase like "on holiday" or drop the "the" as in "going to the hospital", I would be willing to bet that the speaker is a liberal.
I don't see your average Conservative using such silly affectations.
It's a pride in one's own country thing.
Libs don't usually have it.

A popular one today among the young but I don’t know that it’s Brit in origin is:

“Wanna come with?” as in, “I’m going to the mall, wanna come with”?

I’ve forbidden my grand children from using it in my presence.

Talk about someone sounding pretentious, have you ever heard the more than average Conservative Rush Limbaugh pronounce 'schedule'?

That one bothers me too. It's a Canadian thing also so we Michiganders are likely to hear that a lot.
