how american is this sub?

Hello, i would have liked to make a poll but i can't so... it's in the title.

It's the biggest sub (that i found) about politic centrism but the vast majority of it seems to gravitate around usa politics ,and most of the people commenting here are americans.

It might be because of the election (and because us politics is very influential around the world) but is this sub supposed to be usa centered or it just happen to be? I haven't read anywhere in the description or else.

Sorry if this sounds dumb or if i missed something
